White wing patches 5
Start
Congratulations - you have completed White wing patches 5.
You scored %%SCORE%% out of %%TOTAL%%.
Your performance has been rated as %%RATING%%
Your answers are highlighted below.
Question 1
The species is:
Eastern Phoebe
Northern Mockingbird
Loggerhead Shrike
Townsend's Solitaire
Question 1 Explanation:
Question 2
The primary coverts are mostly:
white
dark
Question 2 Explanation:
The primary coverts are essentially all white, with the mostly dark alula lying across them. All of the primaries are white at the base, with only a little white on the outermost and lots of white on the inner primaries. This means that only a small amount of white shows when the wing is folded (the inner primaries are hidden, stacked up underneath the secondaries) and a big white flash appears when the wing is spread.
Question 3
Comparing the two different birds in these photos (the perched bird in the explanation of question 1 and the spread wing in the explanation of question 2), is the pattern of white on the median secondary coverts the same on both of them?
No, the pattern of white is different.
Yes, they both show the same pattern of white.
Question 3 Explanation:
The folded wing of the perched bird shows obvious white tips on the median coverts, forming a second wingbar. On the spread wing these white tips have worn off (click the photo to see in more detail) leaving just a trace of the white wingbar. The presence of melanin actually strengthens a feather, so it is common to see this condition in which the white parts of each feather have disintegrated, leaving only the dark parts.

Update: For future visitors I should explain that I posted this as an April Fool’s Joke. This video converts the voice descriptions from the Sibley Guide to Birds from text-to-speech, and the results are pretty funny, and maybe even a little bit educational.
Today I’m very pleased to announce my latest major project. It’s a bird song identification guide in a format – animated video – that has been entirely, and inexplicably, overlooked by bird guide authors. I’ve been working very hard on this for a while now, so I’m really excited to be able to show it.
Enjoy! And let me know what you think.
