Nest Check Season Begins and Sub-Adults Swarm Missouri

For the last three weeks, I have been swarmed by sub-adult purple martins as they flooded into my site, harassing the already-established pairs.  We must have had a banner year last year and the happy, carefree calls and antics from the sub-adult males as they try to find a mate puts a grin on my face and tears in my eyes as I stop to enjoy the sounds and raw nature of these birds as they focus on their single goal.  Last Saturday afternoon, May 21st, I decided it was the perfect weather to do my first nest check of the season.  With the temperatures being so cold during the prior week and having to feed almost 160 martins, I was dreading nest checks, but I had to know.
As I gathered my tools, the persistent cheeping of the baby bluebirds begging for food from their exhausted parents made it easy to spot this little fellow in the yard.  Unfortunately, I had found feathers from one of his brothers/sisters nearby, indicating the owl had caught one of them.  But this one's a survivor and I was about to discover how my colony was surviving too.

Bob bought a new tool belt for me to hold all the new equipment I now need for my nest checks inside the wire cages.  It has a belt clip on the back to hook over a belt or the waistband of your pants.  It has plenty of small pouches around the outside with a few clips too, and even a magnetized patch for holding screws, nuts or gourd clips.  It has loops inside the main pouch which will hold things in place and a large opening inside for holding bigger items. I've added wire cutters to quickly cut zip ties that hold the wire cage panels on the frame, 3 different sizes of zip ties for various applications, a marker for refreshing gourd numbers, needle nose pliers for pulling the stubborn zip ties tighter, and I put the zip tie discards in the middle open pouch.  As my nestlings get older, I'll safety pin a plastic bag to the side containing an index card.  The index card will be an easy, quick reference list of nest cavities with the older nestlings whose nest needs to be plugged.  This thing has room for much, much more - as long as my pants don't slide down from all the weight.

The martins know what's coming when I enter the yard with my tool belt, my tool box, and my white hat, while smelling like Vanilla extract. The old-timers don't mind - they hang out on the cages and perches, awaiting their turn, while the new sub-adults flush and scream to alert everyone that surely, the Vanilla extract I'm wearing will be used create some tasty dish out of all of them.

The martins in the middle rack await their turn.  They know what's coming. But first, I have to remove the ties that hold each panel to the next, so I can slip inside.

I also use a voice recorder for all my nest checks that I pin to my shirt for easy access.  This helps keep my hands free and I don't have to deal with keeping track of a pen & paper in all the chaos too.  I've had this little thing for the last 6 years and it just keeps going & going.  With 84 cavities to check, it is just another tool that helps expedite the process.

With some dark days behind us with the cool weather and repeated, Great Horned Owl attacks every night, my heart pounded and I could hear the blood rushing through my veins, unsure of what I would find. 

To my delight, I found 54 pair of nesting purple martins, which is 8 pair ahead of last year around the same part of May, along with 264 eggs and 10 young nestlings.  Still, I didn't know which way my numbers were trending, so I waited another week before breathing a sigh of relief with another nest check completed this past Saturday, May 28th.  I am so excited to report my total pair number increased to 71 pair, 306 eggs and 40 young.  YIPPEEEE!!! 

Since adding the roof over the top of the house cage and extending the bottom of the wire, the owl has been visiting less frequently. I've also been going out just before complete dark and shooing the sub-adults off the porches.

In 2014 and 2015, I had 76 total pair each year and this year, I'm on track for the same total, if not more this year.  Despite the best efforts of the GHO, my martins are surging ahead with their work.  Establishing nests, finding mates and supplying food to the ever-growing number of nestlings.  During the day, you would never know what terrors they have experienced.  They may not forget the night before, but they're moving on quickly & efficiently with their lives, obviously enjoying this moment - the present.  I think I need to be more like my purple martins too - enjoy this moment, for today, we are still the survivors.
