Purple Martin Season 2019 Has Begun

Two ASY male purple martins arrived on March 10, 2019 this year. This year's arrival is more back in line with my first 10 year average arrivals.

In all the years past, my martins had also arrived with the tree swallows, however, this year, a male tree swallow had actually arrived a week earlier. During the last few days the tree swallows have been swarming the nest boxes in the fields and my blue birds are not really thrilled with their arrivals.
They are such happy, cheerful little birds and love to fly up high with their bigger cousins. I was going to remove this perching pole this year, but since they seem to like it so much, I may have to leave it...I don't want to upset my fabulous sentries!

This year, I'm making more changes. A landlord decided he wanted to retire his colony, so I bought some of his equipment from him - namely another Super System. It is so much easier to do nest checks with the extended cages on these systems than it is with the round Deluxe gourd rack systems, so this year, I'm removing one of the Deluxe systems and by adding 4 more gourds to each Super system, I'll still be able to offer 84 gourds and my nest checks won't be so painful (literally - it was death by a thousand scratches in the round racks).

So, with this system, I'm designing the cages in the same way - since they work so well on the other racks. I'm extending the 4' gourd arms by adding an 18" aluminum angle arm. I drilled 2 holes to mount the extensions to the main arms, with another 2 holes on the very end, where I can mount the cage wire.

Then, I have laid a 6' piece of aluminum angle arms from corner-to-corner. We drilled holes in each end, so I can anchor them down with tie-wraps. This helps support the top cage wire, so it doesn't sag, and these arms are super-light.

Since I've removed one of the Deluxe round racks and I wanted to keep the same number of gourds, I added 1 gourd per arm on each rack, so I'm still at 84 gourds. For the end gourd, I replaced the straight arm with a 45 deg. arm, which effectively points the end gourd back inside the cage.

For this Super system above, I just replaced all the arms with the extra long arms I had purchased from Hilltop and have made it a perching rack / feeding tray / oyster -egg shell feeder. Bob was tired of seeing me stand on my 4-wheeler to try to fill the other tray on my old post, so we converted this one.

For now, I only have 10 martins here, so I'm taking my time and making sure I have everything the way I want it. Lesson-learned: it is super annoying to get into the heat of the summer with jumpers and not be able to easily put them back into their nests. This Great Horned Owl has made my life more difficult but as she has learned and adapted, so have I.
I'm also keeping the Deluxe gourd rack that I took down - you never know, I may change my mind when I retire and put it back up and expand my colony, but for now, I'm pretty happy with offering 84 gourds that are 100% protected from the owl, yet still being able to perform nest checks.
Lookout 2019 - here we come!

The Grand Finale to a Great Purple Martin Season

After an initial rough start to the 2018 season due to some unanticipated moves by the GHO, I was able to finish the year with a total of 76 pair and we fledged 360 young.

Kicking off this season with a warmer-than-usual Spring, many of my adult pairs were able to get started with nest-building and egg-laying in parallel during the same 2 weeks. This resulted in many, many nests fledging simultaneously from July 3rd through July 14th, with hundreds of martins returning in the evening, filling the arms on the gourd racks.

The new fledging tree behind my house held dozens of newly-fledged martins. As I watched them every day, I worried that the hawks would be drawn to such easy prey, but it never became a problem The tippy-top of this tree is easily 100 feet tall and the new fledges were able to drop and gain speed quickly. They were safer up there than they were on the top perch rods on my gourd racks.

The young fledges demanded food from whomever came flying in, whether it was one of their brothers & sisters or not.

After watching over the young fledges roosting on the arms for several nights and wondering if I was making a mistake by allowing them to roost there, it became apparent the owl had either tried & failed to broach the nets beneath, or wasn't quite sure she could keep from getting tangled in the ropes. Either way, the netting was the final touch to my cages this year that allowed for a nice balance of allowing the martins to escape during a hawk attack, but also kept the owl out (see this post from June, that was the reason I had to install the netting: http://kathyfreeze.blogspot.com/2018/06/nest-checks-new-hatchlings-and-nets.html)

This was the first year in my 12 years of hosting purple martins that I've had this many fledges returning every night.  It was also the first year, the new fledges have been able to safely roost all night on the gourd arms of my racks - protected from raccoons, snakes, and owls.

This was also the first year in the last 5 years of dealing with the GHO where I've felt I have created the best balance between providing protection for the martins and coexisting with both a GHO and a Barred owl.

Instead of the usual fretting, worrying and anxiety, this year was filled with the sheer joy of seeing so many healthy young'uns on the rails and in the surrounding trees.

I'm glad I never gave up the fight and surrendered, because now, I have a lot of experience with what does and does not work when you have to contend with owls.

PMCA Nest Cam is Up & Running!

The PMCA Nest Cam is up and running - what a thrill to be able to see LIVE what is happening INSIDE a nest.  The purple martin nest is located in Erie, PA. A house wren has been destroying their eggs, but the PMCA has now put up a separate nest box to attract the house wrens away (and hopefully, distract them from the purple martins' nest).  The mated pair now have 3 eggs that are due to hatch on July 1st!

Access the nest cam here at this link:  https://www.youtube.com/watch?v=any61aLAtc0

Be aware - if you click on this link, you not be may be able to complete any of the following tasks for the next 30-40 days:
- vacuuming;

- shopping.

Good luck - you have been warned!  Wow, this is addicting and I'm LOVING it (yes, I'm a crazy woman)!

Nest Checks, New Hatchlings and Nets

My last nest check revealed I have 73 pair so far, with a total of 84 gourds offered.  I continue to be amazed at the resiliency of the purple martin, especially since the Great Horned Owl persists with her attacks.  As an added challenge this year, I've also had a problem now with the Barred Owl attacking my tree swallow and bluebird housing.
But for now, back to my GHO update.  On the morning of April 30th, I became quite alarmed to see the GHO has, after 3 years with these cages, now figured out how to get up and inside to perch on the inside arms of the rack.

After 2 days or mourning and feeling sorry for myself, I decided to cowgirl-up and my husband and I designed a "cargo net" style bottom which would balance the need of the purple martins to both exit quickly when a hawk attacked as well as serve to keep the GHO out. With the mandatory requirement of it being "quick release" so that I could continue with nest checks, we purchased some polypropylene rope, zip ties, quick release clips and some garden stakes.  The first 'net' picture you see below has 14x12" holes in it - I can always adjust the size of these holes if the owl gets through, but since the owl's wingspan ranges from 36"-60", I'm hoping I don't have to change these.  The 4 long ropes are crossed by 6 shorter ropes, tied together using zip ties at each crossing.

I've put together the video below to show other landlords how the netting is connected to the cages and how it quick releases for nest checks.  I made a mistake in the video - the rope is called, "polypropylene".  :)

For the round racks, a different approach was used to the the netting.

While the owl has definitely made my nest checks a little more time-consuming, my husband has always helped me come up with ideas to enable me to keep doing them. Given the heat & humidity we experience here in Missouri during the summer, it's imperative that I know the ages of the kids, because inevitably, I will have a few nestlings that will either get knocked off porches or they will jump and I need to know in which nest to put them back.
New "pinkies"!

It was very apparent the nest in the video below had just started hatching.  While it's tempting to help remove the shells from the little, adorable nestlings, because their skin is still so delicate and could be still attached to the shell, I never 'help'. I let Nature take its course - the baby will be stronger for it and I avoid damaging him/her.

The Hidden Secrets of Leaves

The trees are shaking off the last of their dead leaves in preparation for winter. We usually gather them by the wheelbarrow loads and dump them in the raised garden beds and the compost pile, turning everything under so they can help improve the soil for next year's harvest.
As I've written about before, the transition to Fall is my favorite time of year. I think part of my love for Fall is due to the decline in the tick and chigger populations.
Our favorite resident female squirrel (whom we've named, "Olivia") has been a frequent visitor in this part of the Savanna - now we know why. With the leaves gone, we can see her new nest at the top of this oak tree. Unfortunately for her, the Great Horned owl has also found her nest. Several weeks ago, around 11 PM, I was out with Nikki and suddenly the GHO flew out of the dead tree to the right of Olivia's nest, sending more dead limbs crashing to the ground. We've seen Olivia since then, so I'm hoping she has decided to nest somewhere else.

As Fall transitions into Winter, it also provides me with the opportunity to cut back limbs on trees that were allowing the hawks to hide their approaches and attacks on my martins. Apparently though, not only some limbs, but some more trees have got to go, before my martins return in March.

The hawks used this corridor to come bulleting through and surprise my colony.  (the closest tree in front is 150' from my colony)

This winter, it will be a massacre where the trees are concerned. We had a tough end of season with a male Sharpie and a female Cooper's that paired up and wreaked havoc on my colony. As much as I love my martins, I was glad to see the last of them leave in August so I didn't have to watch the onslaught.

Bob and I watched helplessly as martins were snagged in mid-flight, until we put up these barriers to help deter and re-route the hawks.
I hate cutting down trees.  It just feels so wrong. But, if my colony is going to survive and thrive, I need to make some sacrifices.  It always makes me feel guilty when I do it, as I know the resident wildlife are using the trees to raise their young.
As the trees, bushes, blackberries, multi-flora rose and the other varieties of shrubs we have here have shaken off their summer and fall colors, I have started to feel a bit better about the decision to take out some trees.  To my delight, I have found that many more birds are using the dense cover provided by the leaves and brambles, than I originally thought.
In this thicket north of my house, of blackberries, multi-flora rose and buck brush, I had to look 3 times to verify the nest in the middle of the thicket.
(to enlarge the photo, simply click on it).

Check out how well hidden this nest was - dead center of the photo.

Without the benefit of having eggs in the nest, it's always been difficult for me to ID nests, unless they're as obvious as a tree swallow or other cavity-nesting bird.  I believe this one is a robin's nest.

Nest #1 (zoomed in photo of the nest in the thicket above). It seems to have a combination of small twigs and grass.
Updated: a purple martin friend suggested "Mockingbird" nest. I fully agree!

In a nearby thicket to the northwest composed mostly of smooth sumac sprouts, another secret is revealed. This one is a small cup.  This nest is formed out of grass and leaves, so perhaps a bluebird nest?

Nest #2, formed out of grass & leaves. Updated! A purple martin friend suggests this is probably a field sparrow nest!

Only 75 feet south of Nest #2, I find Nest #3.  Another small cup nest, formed out of fine grasses and leaves too. It is fun to think about all the little birds I see flitting in & out of these thickets and how amused they must have been during the summer, as I passed by, knowing what secrets they're hiding from me, just a few feet away.

Nest #3, also formed out of fine grasses and leaves.

Following the trails we have on our 23 acres, I find Nest #4 another 100 feet south. Smaller than the first ones, but also built out of fine grasses.

Nest #4 - formed out of fine grass.

Bob found Nest #5 which was so well hidden inside this cluster of multi-flora rose and tree limbs, that I had a hard time photographing it. But still I managed to get 3 pictures, even though I needed to stop and extract thorns and wipe away some blood afterwards.  How do these little birds do it? This nest is much different than the others - a neat little tunnel formed in the middle of a tightly wound cluster of moss.  Chickadee or tufted titmouse maybe?  Either way, a very smart and wily architect - she put a nice roof over her babies' heads too!

Out in the middle of the south field, tightly wound in the branches of this smooth sumac sprout, is Nest #6. It's so small...I'm guessing a hummingbird nest?  What do you think?

Nest #6

This one is very much a masterpiece, built to withstand the wind and rain, tightly secured to its supporting branches.

Nest #6 - view from the top.

Finally, in the far south of the property, we find 3 more nests. Nest #7 was firmly stationed against this tree trunk on top of criss-crossing brambles and limbs, with what looked like bits of mud, grasses and small, fine twigs. Another robin?

Nest #7 - a bit of mud, grass and small twigs in this one.

I had to laugh at all the pictures I took of the birds' nests - almost every one of them has a stem showing in the picture with buck brush berries on them. Buck brush is one of the main staples of food here in winter, so if the kiddos hatched in these nests are seed eaters, they should be doing quite well right now!
Nest #8 - 100% built out of the native grasses in that area.

Nest #8 - I give up - ideas?

Nest #9 was found among a persimmon & plum tree grove that we've allowed to grow. Another one built out of grasses & fine twigs. Seems too small for a robin.

Nest #9 - grasses & small twigs.

I was able to find 4 more nests, but they were so deeply buried in the thickets it was difficult to get a good picture. Given the multiple predators and issues I have to deal with with my purple martins, it makes me wonder how so many of these nests actually produce surviving nestlings. Seeing the numbers of birds here on Gobbler's Knob indicates they are at least somewhat successful though.
I love surprises and I love that the birds are able to keep their secrets during the summer.  But in Fall & Winter, I get a peek into what they did during the summer and imagine all the little stories that were going on, right underneath my nose - well, underneath the leaves at least.

A Message in a Little Yellow Band

How was I to know that placing a teeny, tiny little yellow band with the number "A407", on the tiny little leg of a purple martin nestling from Trendsetter house - cavity #8 on June 29th, 2011, would bring such a message of hope and inspiration to me this season?  It's funny how something I did 6 years ago - which seems so long ago, yet really not that far - can have such a meaningful impact on my life today.
I had been noticing a few martins with yellow bands on the gourd racks and since the weather was so perfect on Friday, I decided to get out my equipment and spend a few hours with my martins.  This is how I use my vacation time and where I am 100% focused on my martins and nothing else can bother or worry me - in my yard, with my martins and my spotting scope.
But there is a process to prepare for "band-spotting" work and I have a list of what is needed.  First, sunscreen - SPF 50 is required, or my first outing into the sun will result in a very charred, red nose.  Next, a few dabs of Vanilla extract around my nose, mouth and eyes to keep the gnats away from my face.  Sticky, but very effective!  I also carry a small, cheap notepad with a pencil (I prefer pencil, just in case I write down a wrong number) and a set of binoculars for the overall, initial scanning.  I love the yellow Missouri bands that MRBO put on my birds - it makes them so easy to spot.
Bob mounted my umbrella holder on the back of my 4-wheeler for me. I love this thing!  Bob and our recently-deceased friend, Bob Petersen, had come up with this clever design so that I could sit out in the sun, anywhere in my yard, during the heat of the day and spot bands or just enjoy my martins.  Yes, I'm fully aware of how spoiled I am.

The shade also helps keep my spotting scope from getting too hot.  Since it is black, it would quickly overheat in the sun and that's a bad thing for optics.  I see a lot of people on the Purple Martin forums asking what type of spotting scopes to buy to read the bands on their birds.  For me, this little Nikon ProStaff 5 has worked perfectly.  With a 16x48x eyepiece on it, I can sit right in the middle of my colony and read the numbers on the yellow and the silver (federal) bands and observe the unique markings of each individual martin.

 

It's especially challenging at this time of year to read bands as the martins tend to flit around from rack to rack, visiting all the other gourds and other potential mates and that makes it hard to tell to which gourd they belong.  But this time, a couple of them revealed to which gourd they were committed by the persistent wave of green leaves they were bringing in.  I was surprised that they are still bringing in green leaves at this stage of the season, with so many eggs already laid. 

This guy, Mr. A407 was packing in the green leaves for G20.  There are no words to express how thrilled I was when I reviewed his record today.  He was originally born in my Trendsetter (cavity #8) and was banded here as a nestling on 6/29/2011, making him 6 years old this year.  But what made my spotting of him really special - he had also nested in the Trendsetter for the last 2 years.  That means that he not only survived all the owl attacks on the house during that time, he also adapted when he returned this year to find the Trendsetter had been replaced by a gourd rack.  He chose to nest in a gourd this year, meaning yes, he REALLY wants to stay HERE.  Oh, welcome home, you gorgeous, daring & brave young man!  A message of Hope - not in a bottle, but in a little yellow band!

Mr. A407 - now 6 years old has lived to tell the tale of the Great Horned Owl on Gobbler's Knob.

My next ID was of Mr. C226 - now nesting in G1.  He was born here in G9 and banded on 6/10/2012, making him 5 years old this year.  Ironically, G1 is right where G9 used to be, since I moved all the gourds down one level this year so the owl could not agitate the gourds from the top level.  Now how cool is that?  Bob thinks he just likes the view of our home and the feeding tray when there are crickets and eggs served during cold weather.   

Mr. C226 - 5 years old this season.

The last band sighting was of Mr. A673 - he was banded here on 7/9/2011 as a nestling - also making him 6 years old.  He was born on the same rack where I spotted him, but I have not identified his new chosen gourd for this season yet.

Mr. A673 - 6 years old as of 2017.

Last week, I was a little worried as a nest check revealed I only had 60 pair on Memorial Day.  In previous years on the same day, I've had around 70.  Turns out, they were a few days behind this year and as of today, I have 71 pairs of martins nearly filling my 75 gourds I am offering this year.
They all seem to have adapted to the caging around the gourd racks, but it still makes it difficult to get a good picture with all the wire.  Somehow, but we all seem to work around it.

The sub-adults have arrived and are causing chaos with the adults.  I love watching the adults watching the sub-adults.

"Is that your boy from last year, George"? 

One of my favorite challenges when watching my colony, is to try to identify the sub-adult males.  You can usually find them by just watching for the fights and screeching.

As of today, we have not seen the owl in 11 nights.  A friend from the PMCA forum has loaned me his "Dancing Man" and I am trying him out.  I have him on a timer and change the settings for him to turn on and off at different times each night. 

I've also deployed my 'hunting blind' from which I normally hunt English House Sparrows and Starlings, and I've been moving it around the yard every 2 nights.  I purchased some solar yard lights and I recharge one every day and put it inside the blind each night, slightly unzipping the portals so the owl is sure to see the "evil eyes" staring her down if she tries to enter the yard. There is no way to tell yet what is being effective in keeping the owl away, but whatever the reason is, I am grateful for each night she does not come around and I'll just keep throwing out every thing I can think of to keep her away.

For now, my banded 6-year old martins are proof there is indeed a ray of hope for my colony.  I think I need to get a bumper sticker that reads, "My Purple Martins Graduated with Honors from GHO Battle School"..... or something.  Ha!
