A Little Migration, Maybe?

Captain Sam's 
Well, we had a busy day at Captain Sam's but not in the way we would hope!  One of the island's bobcats was recorded near our banding station early this morning and in order to prevent her from coming across a captured bird, we checked our nets constantly.  Good news: No sign of the bobcat.  Bad news: Our total was a mere 7 new birds and 7 recaptures.  Checking the nets every few minutes likely contributed to our low capture rate but the safety of the birds is our priority!

Little Bear
There were some signs of migration happening today out at little bear! We had some ducks zooming by over head as well as a few new migrant captures today. Our total captures today amounted to more birds than we have captured in the last three days combined. Though these numbers are unseasonably low, we are hopeful that migration will pick up more and more as weather systems to the west of us are moving on. We did have one pretty exciting capture today! A second of the season Clay-colored Sparrow! This bird was a little more dark in color than the last one captured at Little Bear this year. Notice the characteristic gray nape, lack of streaking on the breast, streaking present on the crown, and the buffy color of the rump. These characteristics can be used as field marks to notice when plumage color variations make them confusing. 
Clay-colored Sparrow (Hatch-year, sex unknown)

Lack of streaking on the breast!
Notice the gray nape!
