The bird that you have labeled Orangr-crowned Warbler is a female Yellow
Warbler. The Empidonax species I am struggling with to identify. Certainly
the bird labeled Empidonax 2 has a very long primary projection and looks
Wood-Pewee-like. Looks good for Willow perhaps. It has been a while since I
have observed rapid plumages...

Thanks for sharing,
