The new birds on the block

Recent (re)arrivals include:

• Catbirds (http://identify.whatbird.com/obj/557/_/Gray_Catbird.aspx)
• Yellow warblers (I think--they move very fast) (http://identify.whatbird.com/obj/343/_/Yellow_Warbler.aspx
• Little finches with red heads? I haven't identified these yet... almost sparrow size, brown and cream body, red heads...
