Solution to topside quiz from The Crossley ID Guide

A few days ago we posted the first glimpse of a mystery plate from The Crossley ID Guide: Raptors. Hopefully you had a chance to post your guesses.

Here’s the plate to refresh your memory:

And now here is the solution to the quiz:

1. Juv./1st-year Swainson’s Hawk. Dark brown on top with blackish flight feathers and tail, pale uppertail coverts, and obvious buffy fringes to upperwing coverts. Note long, tapered wings.
2. Juv./1st-year Swainson’s Hawk. Dark brown on top with blackish flight feathers and tail, pale uppertail coverts, and obvious buffy fringes to upperwing coverts. Note long, tapered wings.
3. First-spring Golden Eagle. Dark brown on top with a golden wash on head, and white-based tail. Note that 1st-years in spring have a broad fade to the upperwing coverts that resemble the narrow, pale mottled upperwing bar of older birds. Also note shorter inner primary still growing in.
4. Adult Bald Eagle. Unmistakable, uniformly dark with a white head and tail, and large yellow bill!
5. Adult Golden Eagle. Overall brown above with paler mottling along the upperwings, golden head, and grayish bands on tail. Note, in bright sunlight, grayish areas can look white.
6. Juv./1st-year Red-shouldered Hawk. Brownish on top overall with translucent primary “commas.” Note squared-off wings and somewhat long tail with indistinct banding.
7. Juv./1st-year Northern Goshawk. Pale underneath with heavy dark streaking throughout. Note somewhat short wings that are very broad but taper at the hands, a broad chest, and long tail.
8. Osprey. Blackish on top with a white head and black eyeline. Note white underbody and long, narrow wings. An adult based on pure white chest, and lack of dark streaking on crown.
9. Juv./1st-year Sharp-shinned Hawk. Dark brown on top with faintly banded tail. Note long, narrow tail, short, broad wings, and small head.
10. Immature Bald Eagle. Dark brown overall with blackish flight feathers. Note significant whitish mottling in tail and uneven secondaries denotes sub-adult. Also, note browner back with darker upperwing coverts. 1st-year is even-toned throughout back and upperwings.
11. Adult Red-shouldered Hawk. Plumage is a beautiful rusty underneath with a brown head, and blackish on top with clean, narrow white bands throughout the flight and tail feathers, and whitish comma-shaped primary windows.
12. Adult Red-shouldered Hawk. Rusty underneath with a brown head, and blackish on top with clean, narrow white bands throughout the flight and tail feathers, and whitish comma-shaped primary windows. Note reddish “shoulders” of adult.
13. Juv./1st-year Broad-winged Hawk. Brown on top with slightly paler primaries, faint pale mottling on upperwings, and indistinctly banded tail with darker band at tip. Note stocky, pointed wings and large head. Tail appears somewhat long on 1st-years.
14. Adult Red-tailed Hawk. Dark brown on top with a bright rufous tail, and golden wash to head. Rufous uppertail coverts rather than whitish much more common on Western race than Eastern.
15. Juv./1st-year Red-tailed Hawk. Indistinct plumage. Brown on top with pale uppertail coverts, and pale mottling on upperwings. Note long but broad, bulging wings that taper slightly at the tips.
16. Juv./1st-year Cooper’s Hawk. Dark brown on top with faintly banded tail similar to Goshawk but lacks the pale mottling along the upperwings, and pale eyeline. Note long tail with obvious white tip, short, broad wings, and noticeable head projection. Wings and tail are slightly longer in relation to other accipiters.
17. Osprey. Note blackish topside with white crown, and very long, narrow wings. Aged as adult based on lack of pale fringes on upperwing coverts.
18. Juv./1st-year Northern Goshawk. Brown on top with tawny-streaked nape, pale mottling on upperwing coverts, whitish eyeline, and long banded tail. Note broad wings compared to other accipiters.
