[cobirds] RMBO Chatfield Station Report, 5/21/12

Second day with reasonably good numbers and fun birds.  31 banded and 1 return (plus lots of recaps-mostly Yellow Warblers-from earlier days this season which I’m omitting from the report):

 

Least Flycatcher                1

House Wren       2

Marsh Wren       1 (FOS, likely only 1 of season)

Gray Catbirds     6

Yellow Warbler 12 new, 1 banded last year

Yellow-rumped Warbler, Audubon’s       1 (FOS – POR FIN!)

Common Yellowthroat  1

Yellow-breasted Chat    2

Western Tanager             1

Song Sparrow    1

Lincoln’s Sparrow             1

Black-headed Grosbeak                1

Lazuli Bunting    1

 

Did a little review of data last night.  Our numbers are way down this year (40% lower than the same days last year).  Seem to be missing birds that would be passing through.  The opposite seems to be true with our likely resident Yellows and Catbirds – they are coming back slightly sooner and/or in greater numbers.  Haven’t check the House Wrens or Chats yet, although they seem to be down.

 

Don’t know what today’s heat will bring, except a likely early closing…….
