Question 1

The species is:Northern MockingbirdTownsend's SolitaireEastern PhoebeLoggerhead ShrikeQuestion 1 Explanation: Question 2The primary coverts are mostly:darkwhiteQuestion 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 3Comparing 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?Yes, they both show the same pattern of white.No, the pattern of white is different.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.
