The Littlest Falcon

Three different species of falcon call Connecticut home, Peregrine Falcon, Merlin, and American Kestrel.  The American Kestrel, the smallest of the three falcon species, is an open prairie or grassland hunter in general, feeding on almost any small moving animal.  They are known best for their love of grasshoppers and dragonflies as food for their young.  Unfortunately, this habitat is becoming compressed in the state and compounding that with a reduction in nesting spots, the population of nesting kestrels has dropped.  Recent efforts by bird lovers such as Art Gingert and Tom Sayers have helped these falcons bounce back, if even just a little.

Now for my story:  Yale's West Campus is approximately 130 acres, many of it wooded, but the majority is landscapes lawns and some natural grassy areas.  We have been working to encourage the landscapers to retain as much 'natural' habitat as possible in hopes that it will attract more bird species.  Our current species count on campus is at over 100 and American Kestrel is one of those we have seen on frequent occasions.  So, it didn't take long for us to begin to wonder if maybe a kestrel would want to use campus to raise their young. 

Sue (my coworker) and I decided to try and get a nest box to hang in one of these natural grassy areas.  We made contact with Art Gingert who supplies nest boxes in suitable habitat but he felt ours was not good enough quality to be able to give us a box, when other better habitat was in need.  We however, have a tough time giving up so easy and instead dug into our pockets and pulled together enough money to buy the supplies to build our own box.

After months of delay (it was winter anyway), we volunteered Nate another coworker to help us put together the box.  After about 7 months of the wood sitting around, two weeks was all it took to get the box together and ready to hang.  Last Wednesday was a nice sunny day, we had some spare time, and a nest box ready to hang.  Here are a series of pictures from the afternoon.

If you have an interest in learning more about American Kestrel, information can be hard to find, I'd suggest starting here

Information about Tom Sayers work in CT can be found here.

Directions from Art Gingert on how to build a nest box can be found here

We are keeping our eyes on the box and around campus in general for kestrels.  I'll keep you posted with any updates.
