    Any thoughts on this as a Golden-Crowned x White-Crowned hybrid?  I know that the crown pattern for GCSP can be rather variable, but the pattern on this bird is fairly crisp and the black stripes seem to align well with WCSP.  The bill is also a bit more pale than a GCSP.

  2. If #1 is the same the individual in #4, I would lean towards Least given size alone.  Also, the base of the bill tends to be more yellow in a Pectoral (tough to see really in the photo though).

    #2 looks good for a Semipalmated to me.  The short, straight bill, coloration and somewhat "bull-necked" appearance align with typical traits of the species.

  3. I believe that one differentiator is the dark line through the eye.  Philadelphia goes all the way to the bill while the line on a Warbling tends to get paler as it approaches the bill.  That said, it is subtle and tricky for these photos.  The first photo would suggest Warbling to me but more input is needed from those who regularly separate these species in the field.

    Another for the classic raptor ID challenge...

    This individual was quite small and I initially ID'ed as a Sharpie in the field.  However, after photo review I'm leaning toward male juvenile Coopers.  What do you think?

    • Eye placement more toward the front of the head (eye color seems to align with Coopers but that's tricky in low light)
    • The breast pattern is a dark brown and seems "neat".  It is hard to tell if the pattern thins out on the belly in these photos.
    • The head seems blocky, but I'm hesitant to rely on that given the angle.
    • Legs seem a little more robust than a Sharpie's
    • There is a light supercilium but it seems rather faint.

    Unfortunately I was not able to see it in flight.

    Thanks!

    I noticed what appears to be a Brant among a large flock of Cackling Geese today (poor but usable iPhone photos attached).  My leaning is that this is a juvenile Brant but wanted to get opinions from those better versed in the species.  A Brant would generally not be expected at my inland location but is not unheard of.

    Thanks!

  6. I've been discussing this buteo with local Benton Co., OR birders but could use more assistance.  My initial, naked-eye impression was immature RTHA, but my bin views while the bird was transitioning to its "perch" showed clearly feathered tarsi.  I then grabbed the camera aware that this is a bit early for the species (10/7).  Unfortunately the photos don't offer as clear of a view of the tarsi given the posture and lighting.  The plumage doesn't initially suggest RLHA but after reviewing multiple guides & sites on this I came across a decent number of RLHA photos that seemed to match the plumage features.  Here is a good example:
    Another found via google image search but I'm not sure how accurate the source is:  https://pixels.com/featured/immature-rough-legged-hawk-dennis-hammer.html
    Thanks!
