"I come into the peace of wild things who do not tax their lives with forethought of grief. For a time I rest in the grace of the world, and am free." ~Wendell Berry
Using the lessons I learned from the last birdbath I poured, (see that project here: http://kathyfreeze.blogspot.com/2014/08/making-it-way-you-want-it.html, and here: http://kathyfreeze.blogspot.com/2014/08/success-is-in-eyes-of-beholder.html),
I decided to pour the second one this week. I've been asked by a few people how I did it, so this time, I'll list the supplies and a few more details.
First, determine what shape you want. I found my planter pot saucers at Lowe's for about $5 and the large one is just the right size for the bath that I want.
I use this 'Quikrete' concrete mix (already has the appropriate sand and concrete blend) which can be used for paving bricks.
I also add this Concrete Acrylic Fortifier - it helps increase bonding and water resistance. For color, I like the 'Terra Cotta' color, but there are others available. All of these things were purchased at Lowe's.
This time, we're using sand. Much easier to work with. Normally, it's recommended to use "Casting Sand" when pouring concrete molds, but we're using 'Paver
Sand'. The Casting sand is not available around here and, after finding it online and seeing the price, I was quite happy to just work with the paver sand.
Bob framed up a box that is approx 4-5" bigger than my mold, to help hold it all together.
First things, first - find a place that is in the shade all day, so you
can work comfortably, and also has a source of water nearby. You will also want your freshly-poured birdbath to be in the shade for at least 48 hours, so that it doesn't dry out too quickly.
Since I'm making a total of 3 bird baths and I want the water to flow from one to the other, I also added pour spouts on each of mine. The bottom one will pour into a 5 gallon reservoir, in which I'll place a water pump to pump the water back up to the top bath. If you're just making a simple, single bird bath, you don't need a pour spout.
Place your chosen tray upside down in your box, then pour in your sand. Wet
the sand thoroughly. You will need something with flat sides with which to pack the sand (I used the small stick in the picture to pack it with), then
hollow out every place you want concrete to flow into. I found a trim tile piece to use for the shape of my spout. Make sure you wrap it with Saran Wrap, or you will have a heck of a time getting it unstuck from the concrete.
My planter tray, turned upside down, the piece over which I'll pour the concrete for the spout, the stick I use to pack the sand down, and the wooden spoon that I scrape around the outer edges to shape the sides of the bath.
A closeup of the tile piece I use to shape my spout. This was exactly the shape & size I needed for my spout. Wrap it in a non-stick material, so you can remove it after the concrete hardens.
I used a wooden spoon to pull out the sand around the edges of my mold as it was just the right thickness for my bath - about 1.5" wide and I could ensure my sides would be even. You can adjust your bath to be more shallow by leaving more sand around the edges of your mold (the trough area), but for me, it was easier to just adjust the depth of it by making my spout higher or lower on the side of the pan. Now is a good time to place any decorations for your bath on top of the mold and in the trough areas. Last year, I used leaves from my sycamore tree and cucumber plants. Remember - you have to think 'upside down' when you're carving your mold out of the sand. It's also really important to pat your concrete down into the mold as you pour it, so that you don't end up with creases and air voids (see the pour spout on the bath below as an example of what it will look like if you don't pat it down enough). I did a great job around the edges of this bath, but the spout came out kind of rough looking. I try to work quickly with this stuff, because I'm afraid it's going to setup before I can get it tapped in. Lesson learned - slow down and work each edge thoroughly.
For this birdbath, I used scraps of stained glass that I had been saving. After turning the bath over (we waited about 24 hours), I found that the concrete had slid under the glass and encased it. Thankfully, the concrete wasn't fully hardened off and I was able to scrape some off to reveal the glass underneath.
The finished bath - the overflow spout is kind of rough looking, but it's functional. Next time, I will use bigger pieces of glass also.
I poured the leftover concrete into a few smaller sized planter saucers that I had lying around to make some stepping stones for my garden. I also pressed some scrap stained glass into the tops of them, working them back & forth to get them secured into the concrete. The biggest mistake I made with these was the planter saucers are made of ceramic and I couldn't separate them from the concrete afterwards. So - lesson learned - either put down Saran wrap before pouring into a ceramic mold or use plastic molds. Make sure you look at the molds you choose very carefully. The concrete tends to take on the features of your mold very nicely (look at the ridges in the picture above), so make sure you like the designs in your chosen mold - because that's what you're going to see when you tip the bath out.
This year, I decided that I wanted a wide-angle view of my entire colony at night, from a general monitoring viewpoint, allowing me to also see what may be skittering around my yard. So, Bob did some research and found a reasonably priced Foscam security camera and hooked it up about a week ago. We've been struggling with the range of the IR (60') and really not wanting to run power out into the yard to get the camera closer to the racks. In my last post, I also mentioned that I was trying out a motion detection light and thought that may help scare the owl away if he ever came into the colony and triggered it on. But since 4/18, I hadn't seen the owl and couldn't prove my new tool was working. In fact, I was beginning to think he was filling up on my neighbor's guineas, whose numbers have gone from 20+ to 3 or 4 now. I hear they taste like chicken. That's the word I'm spreading anyway - 'EAT MOR GUINEAS'.
Yesterday (5/18) I pulled my game card cameras for review and found this video date / time stamped at 5/15/2015 -2:35 AM. It was a bit alarming and given the perspective of the camera, I couldn't tell what mischief Giselda had been engaged in before she landed on top of that pole.
The videos recorded through the Foscam camera were taking too long to scan, so I hadn't reviewed them in a couple of days and besides, the IR range and lack of illumination issues were bumming me out. But somehow, on this night, the stars aligned, the winds were perfect, there was no rain, glowing eyes aided in tracking and the lovely glowing cobwebs added just enough annoying creepiness to make the video below quite interesting. And I now have confirmation that a motion detection light is spectacularly useless in helping to scare a GHO away from your colony. But it does provide some nice lighting for recording what she's up to.
I've done some cropping in the video to remove a total of almost 4 minutes of the owl turning his head away, because you really can't see anything when his glowing eyes are not looking towards the camera. I also removed the first 2 minutes of the video where he entered stage-right, landing on the ground about 15' west of the most west rack. I saw his glowing eyes through the noise on that side of the frame and thought for a bit that it must be a cat, a racoon or a coyote. That is, until I got to the 2:23 minute mark and all doubt was removed - (at the 2:23 minute mark - watch the top of the leftmost gourd rack). You have to watch the video at full-screen and watch along the right hand side - you'll see his glowing eyes periodically and her movement as she apparently glides (I don't think a GHO would run) along the ground.
This video served to provide me with a lot of relief - JOY! Apparently, on this night anyway, she wasn't there to hunt for martins. She was there chasing or hunting voles, moles, mice or snakes that were creeping along the ground. Whew! What a relief! She can have all those varmits that she can catch! That $79 camera just paid for itself in saving me a lot of worry & sleepless nights. For now, my guards are still working and she seems to be ignoring us.
So, new plan - I'm putting my scarecrow back in the yard (she was inside that night, due to expected rain) and we're installing bright spotlights that will aid in video monitoring. Enough fooling around. The cages are working - I just need to know what she's doing. Maybe "want to know" is a better description.
Sssssshhhhhhh, be very, very quiet, my lovely darlings, for ye know not what lurks beneath. Or above.

Last Saturday night as I sat on the porch around 9:00 PM, I made the
decision that Sunday, I would get up at 4 AM - prime start time for the
dawn song. As I listened to the little padding, skittering feet in my gutters
just over my head for the next 30 minutes though, I almost changed my mind. Back & forth the
mice were scampering about...at least, I think they were mice. When I
thought I heard one on the rail alongside me, I decided to pack it in.
Mr. Freeze was in bed already snoring and with Nikki inside also, who
would rescue me if the mice executed a coup and had me trussed up in the yard like Gulliver by morning?
Change of plans - I would
still get up but I was going to change my location to the basement
patio away from the gutters. Plenty of room to move far away from my gutter-cleaning mice.
Let me start this post by saying, I am not a morning person. It's just
not in my nature. I'm a night owl. I do some of my best thinking late
in the evenings, especially after the majority of the population on my
continent has gone to sleep. But last year, after experiencing my first owl attacks, out of necessity, I stayed up all night and had the most awesome early morning experiences I've ever had and I want to do it more often.
I grudgingly set the coffee pot to go off at 3:40 AM and my alarm clock for 4 AM.
This year, along with my scarecrow, I'm trying a new approach with the owl. Instead of leaving the porch lights on constantly and directed at my colony all night, I've deployed a new, motion-detection, solar-powered 850 lumens LED light. The idea is that it will react to him by turning on when he comes into the colony, hopefully making him think someone is physically in the colony and they turned it on. My game camera took a video of the Trendsetter rocking to and fro the night of April 18th. The light switched on and apparently he took off. We haven't had any attacks in the last 3 weeks, so I'm cautiously optimistic at this point that the light is helping.
Artificial full moon in my back yard. The light is far brighter than it appears in this picture. Almost blinding when you're in full darkness like this, but I had no idea how to set my camera to get a true representation of how bright it was and was annoyed just enough to not care at the time.
The information on the light says it has a 70' range with 180 degrees of detection. At 4 AM Sunday morning, it was on when I first got up and glanced outside. You can select the number of minutes it will stay on and I had it set at 1 minute. After getting your eyes adjusted to the darkness, that one minute of bright light seems like an eternity.
Apparently, it's also very sensitive. The blasted thing came on every few minutes, reacting to every single martin leaving their housing to dawnsing. At first, I thought it was funny, but after about the 10th or 11th time, I was annoyed with it and thought what a dumb bunny I had been to face it towards my own house. This weekend, I'll be moving it to the other side of the colony, where it can't blind me in the darkness. It didn't appear to phase the martins as I could hear them starting their song after they exited, then a few minutes later, high in the sky, singing away.
Full moon peeking through the clouds - 5/3/2015
By 4:15 AM, I was outside with a full cup of coffee, my camera and a bucket of coffee for refills. Just me and my martins, the frogs, the tree swallow - the little stinker - who insisted on doing a close flyby, and many other animals that I just prefer not to think about when I'm standing alone in the darkness. The full moon, peeking through the persistent black clouds made me think of every scary movie I've ever watched. Enough of that. You can't think of those things while standing in the dark by yourself or you won't enjoy the magic that's about to happen. By 4:20 AM, I had tuned my ears to block out the other noises and listen for the martins that I knew were above me in the sky, but which I still could not see. And then I heard the first one. There's the Magic!
Much to my surprise there were many, many more in the sky already, their song echoing through the trees north of my house. Their song carries extremely well at this time of morning, due to the drops of moisture in the air. From the PMCA site:
"Dawnsong is a unique set of vocalizations performed by adult male martins during the predawn hours of spring
while flying high above their colony sites, or while perched nearby. It
is a loud, continuous series of chirps presented in a syncopated series
of about seven to nine notes repeated over and over. Each male flies
his own path in slow, wide circles about 500 feet up, singing his own
unique song. It is estimated that the sounds from a morning of dawnsong
transmit to about 100 cubic miles of air volume." (Hill, James R., Purple Martin Dawnsong, For Attracting Martins!, pg. 3.)" http://www.purplemartin.org/main/Vocalization.html
Full moon setting - 5/3/2015
After reading multiple posters posting on the internet about why they thought the purple martins dawn sing, I asked Louise Chambers (PMCA), if anyone really knew why they do it. Louise responded,
"Gene
Morton's dawnsong theory was that adult males perform it after their
mate is committed and their paternity is assured - it's safe, at
that point, to invite sub-adult birds to join the site, so the senior males
can have extra offspring via the sub-adult females. So dawnsong will not be
performed until green leaf stage of nest building"
Sunrise - 5/3/2015
By
5:40 AM, they were starting to trickle back into the colony and this one
decided to do an encore performance on right there on the racks. I'm
sure the residents still inside their gourds trying to sleep really
appreciated his chortling at their front doors. I personally really
appreciated his performance, as I could make out his mouth, throat and
general animation during the calls to be interesting too.
My martins have been dawn singing now for a week. It's great to listen to a cd or listen to these recordings, but if you've never gotten up in the morning to listen to them, I encourage you to try it at least once. If you love purple martins as much as I do, I guarantee you, it will touch your soul. They are so free, unafraid and untethered and I feel honored to share in these special hours of pure joy.
A lot of people zip through their lives desperately trying to find something special, something fascinating and thrilling to help brighten their days, something to excite them, never knowing that it is and always has been right there in front of them the whole time - they need only to stop, look and truly breathe it in and enjoy. Who needs to spend barrels of money on vacations and stressful travel, when you can grab a cup of coffee and walk out in your backyard to experience such thrills?
Sunrise - 5/3/2015 - Can you spot the Purple Martin?

One of my fellow purple martin landlord friends, Mike Salcido in Texas took this video this week of a baby purple martin hatching from its shell. During a nest check, Mike discovered that the egg was 'capped' (another egg had hatched in the nest and a part of it rolled over and stuck to this one, make it a double-walled shell). Babies are unable to break through 2 layers of egg shells and will die inside, if the extra cap is not removed quickly.
This is just another example of why nest checks are so important, so you will know the timing of hatching.
Enjoy the video - it's the first time in my 9 years of hosting martins that I've gotten to actually watch the process! It's guaranteed to make your day.
Thanks for sharing, Mike!
For the second day in a row, I have had to rescue a female purple martin who had been forced down in the wet grass by several, hormone-driven male martins. It's mating season here on Gobbler's Knob and across several states. With the rains and dew making the grass and grounds very wet, it's important to keep an eye out for females whose feathers have become so wet that they can't take off. They are extremely susceptible to hawk attacks and racoons if left on the ground overnight. You can often determine that one is down by just observing your colony - watch for multiple males landing on one spot on the ground or flying over that same spot many times.
If you find a downed female in your yard, use a towel to toss over her when trying to catch her - this will help calm the colony as you retrieve her as well as stopping her from trying to flop across the grass to get away from you. Put some pine needles in a 5-gallon bucket, per her in and cover the bucket with a towel and a board across the towel (to keep her from flying out inside your warm room). Place her in a warm environment and as my friend Louise Chambers (PMCA) reminded me this morning, you can turn a heating pad on low setting and place it under the bucket - that's key - do not place it in the bucket.
It looks like the majority of my adult martins are now paired up. They were working feverishly on their nest-building tasks during the past couple of weeks, however, since this past Monday, they've had to spend a lot of time guarding their cavities and fighting off the new arrivals.
But who says that they can't squeeze in some nuzzle time while guarding their cavities?
I watched this couple for close to 20 minutes. They're so close that it made me wonder if they were old friends from previous years too.
Sometimes, you just need a few quiet moments and a shoulder to lean on.
And everyone has started their annual trek to tear the leaves from Mr. Freeze's poplar trees. He wonders why his trees won't grow. I don't show him any of the incriminating evidence such as that in the below pictures.
Many leaves were being shredded yesterday and today. The bright, warm sunshine is so conducive to nest preparation. The martins are taking full advantage.
On Monday, April 27th I filed my report for the first Purple Martin Sub-Adult arrival in 2015. It was late evening and I couldn't get a good picture of him because he kept falling off the porches and perches. Not on purpose. The adult male martins were hard on his tail, pulling the little gangster off their cavities and out of their gourds. I love the fearless and recklessly brave sub-adults. They are so much like human teenagers - they come home from college, eat all the food in the refrigerator, play their music as loud as it will go, stomp around the house and drag their friends in at all hours while you're trying to sleep, challenge the parents' authority, kick the doors in to find their girlfriends sleeping with another male and in general, just make a mess of things. These guys are no different.
If this sub-adult in the picture below, manages to hold onto and move into this cavity on the Trendsetter,
it will be the first time in 7 years that I've had a sub-adult in that
house. Since it's my oldest housing, I've had nothing but adults in the house for a long time. So, either some of the older adults moved to the
gourds, or they have passed on.
Notice the small, purple feathers on his chest and under the chin of this sub-adult male. I've learned to spot them just by watching for the martins that are causing the most trouble. Note his "I'm going to kick someone's butt" posture too.
Sometimes it can be very difficult to spot a sub-adult male in your colony, but other times, it can be quite easy. The most obvious identifying factor is the classic male clicking that they do to attract mates. If you see a martin that looks like a female but it's doing the clicking, you can be 100% sure it's a male. The other identifying factor is to look for purple feathers under the chin or on the chest. Sometimes, there will even be one on the lower part of his abdomen or under his tail. They can be very subtle, sometimes only a single feather or two as with this guy. Other times, it can be quite obvious and the subbie will have a whole head & chest full of purple feathers.
Other identifying traits - watch for the classic 'I'm a troublemaker' posture and usually the one getting his butt whipped by the other males is the youngster that thinks he can swoop in and steal the others' mates for which they've worked for weeks to attract.
An adult female paired with a sub-adult male. Once the sub-adults have paired up, they usually settle down and focus on nest-building. Note the purple feathers on this male's chest and under his chin.
My racks have been filling up for the last 4 days with more martin arrivals.
I can always tell who the newbies are as they try their best to navigate the fencing while still looking cool.
Stay on the lookout for the sub-adults at your site in Missouri. We're halfway through migration at this point. And if you have a new site, now is the best time to establish a new colony.
This blog entry was written by my good friend in Corpus Christi, Mr. John Barrow - purple martin landlord expert and all-around, good guy extraordinaire. His wife, Louise, is pretty cool too.
Thanks for sharing, John!
A lot of birds are migrating into South Texas right now. For several
weeks we have watched kettles of hawks and kites flying overhead. Those
raptors do not cross the Gulf, but rely on heat thermals to carry them
from South America to places farther North, utilizing as little wing movement
as possible.
Late yesterday afternoon I did a nest check on my
martin systems. Looking overhead, I saw several large kettles of Mississippi Kites
migrating northward-several hundred for sure in 3-4 kettles.
Later, as darkness approached, I saw some of my older birds leave the
housing and fly up to intercept groups of incoming migrant purple
martins. Most likely the newcomers are SY (sub-adult) birds. From my small slice of
earth along the Texas coast, I estimate that the number of SY arrivals
was between 150-200. They literally filled my view of the sky, and
returning ASY birds were typically followed to our systems by 10-12 new
arrivals.
Tonight with the arrival of strong north winds, the
late evening show repeated itself. Several hundred new arrivals filled
the sky--most targeting our systems as a stopping point. With nesting in
progress local birds will try to lead most of these arrivals to a
nearby tree to roost or a vacant housing system to settle down near
(looks like about 20 chose the oak tree adjoining my property).
I
mentor at least a dozen landlords in this area--all are capable of
attracting to their sites what I have witnessed tonight. The same is
true for contacts I know up the Texas coast and in to LA. What I have
observed signifies a large General Arrival, with a high percentage of
the SY population entering the USA in advance of, and with the
occurrence of the passing frontal system. This is the heaviest
arrival of SY birds I have witnessed to date, indicating that general
migration is still running about two weeks behind, and with the
opportunity to extend huge arrivals into the USA for the next two weeks,
before migration begins to taper off.
Still lots of time left for
those seeking martins. I would say when these birds arrive mid
continent in 3-5 days, *Halftime* will have been reached in Missouri.
John Barrow - his signature reads, "TEAMED WITH A MARTIN GODDESS". Methinks Mrs. Barrow is a very fortunate lady.
Mr. Barrow's colony in Texas
Purple martins on the Texas coast. One of these could start your colony.
Via Mrs. Barrow on the PMCA forum: Neat video taken today on the Texas coast - these
birds were in the road due to cold temps which left the asphalt the
warmest place to be. The martins look so huge next to the smaller Cliff
or Cave Swallows! Hopefully any traffic took it slow. Here in Corpus
Christi some of our martins were in the street this AM, overnight temp
was in high 50s, and daytime temps got into 70s, providing some good
feeding weather for our friends. It was doubtless cooler up the coast
at location of video.
