  1. BIOL 4142 Photo Quiz Lab 4 Ornithology birds: First, you’ll see a photo showing just enough to allow you to clinch the ID. Then, you’ll see the full photo without the name, and then the photo with the name and perhaps some ID tips on specimens (not field ID).

  2. Not even E. Bluebird would have the “red” extend that far into the belly, and E. Bluebird’, and E. Bluebird’s primaries are blue. American Robin (Turdidae)

  3. Note: not only would a wren lack the stiffened shafts of the central rectrices with bare tips, but also all wrens have barred rectrices. Brown Creeper (Certhiidae)

  4. The only two all-black birds are the two crows. From there, use wing formula … which is hard to tell in photos, but here #9 seems to be substantially longer than #5 American Crow (Corvidae)

  5. Clean white throat and distinct brown breast band Bank Swallow (Hirundinidae)

  6. “Blue” above, pale gray below, distinctive black line on forehead extending to anterior portion of superciliary. Note also black and white tail. Blue-gray Gnatcatcher (Polioptilidae)

  7. Blue Jay (Corvidae)

  8. Black crown, white face, black throat; also note small, short bill. Carolina Chickadee (Paridae)

  9. Brown crown, white spot on nape, blue-gray back …. Brown-headed Nuthatch (Sittidae)

  10. Note pale superciliary, messy breast spots, messy wingbars, and vague streaks on back. All you could see in the first photo was white in outer rectrix, a long nail on hind toe 2-3X longer than the other toenails, and a hint of streaking on underparts … and that’s all you need. American Pipit (Motacillidae)

  11. “Orange” rump, pale forehead, chestnut throat … Cliff Swallow (Hirundinidae)

  12. Carolina Wren (Troglodytidae)

  13. Cedar Waxwing (Bombycillidae)

  14. Face pattern unique; note that the horns will be flattened against crown on specimen. Bill intermediate between insectivore and seed-crusher. None of your other birds has a hind toenail that is straight and 2-3X as long as other toenails. Horned Lark (Alaudidae)

  15. The barred remiges get you to “wren”; then, plain brown back eliminates all but Winter. Relatively long tail and relatively pale underparts eliminates Winter House Wren (Troglodytidae)

  16. European Starling (Sturnidae)

  17. Wing formula 9=5 = Fish Crow Black primaries and underwing coverts = crow Fish Crow (Corvidae)
