30 May 2015 – Tufted Titmouse

Imagine you are holding a deck of cards.  Now toss that deck on the floor and look at all 52 of them.  Now imagine that each one of those cards represents a different species of bird.  There are sparrows, warblers, thrushes, woodpeckers, etc. With the addition of a Tufted Titmouse this morning, there have now been 52 different species of birds killed in window collisions at the Noble Research Center since I started keeping track in 2009.

Of course, this isn’t the first time I’ve featured Tufted Titmouse on this site: On 24 May 2012, I found a Tufted Titmouse at the Kerr-Drummond residence hall immediately to the west of Ag Hall.  That was unusual in that it was a female with a brood patch and she had actually lain down fat (I scored her as a 1).

Today’s bird was similar:  She was a second-year female with a drying brood patch and fat I would score as a 2.

According to Yogi Berra, “You can observe a lot just by watching.”  My watching has just suggested to me that 100% of the Tufted Titmice that have struck windows on this campus have been females in the last week of May with some fat accumulation in the furcular hollow and a brood patch suggestive of having recently produced fledglings.  Is this post-breeding dispersal?  Wandering to find a mate for a second brood?  Wandering after loss of a brood? Dispersal to a molting area?  Questions abound, but with my n = 2, it looks like the beginnings of a pattern to me.
