I know these are next to impossible but I have thought that before...
Bird #1 only have 2 shots from below it
CLOSED: Is there any hope
#1 American Goldfinch - note stout pinkish-orange bill, plain bright yellow underside, white vent, white undertail with black edges.
#2 Tough with it being so blurred and hard to judge size. The blackish line round the face on the last pic makes me think Blue Jay; is that OK on size, behaviour, etc.?
Oops! The one on the wire is definitely a jay... wrong pic!! LOL
The one on the grass was not a jay. Oh well...
Did wonder if the 3rd and 4th pics could be different birds! They don't look the same!!
Sorry, #3 is too poor a pic to identify.
