D (0:33-0:44). Here are the typical calls of these two crows, uttered in succession, the throaty caw-caw-caw of the first crow followed by the slightly longer caaw-caaw-caaw of the second bird (figure 19D, page 139).
Bird 1: caw caw caw
Bird 2: caaw caaw caaw

E (0:48-0:55). Most of the time the two crows call with their distinctive voices, but here the second crow matches the first, each of them using the shorter caw. But alas, I do not know which bird is which! If I use A to designate one bird and B the other, hear what I believe is the following sequences of caws: A A AB AB AB AB AB A. Bird A calls eight times, Bird B five.
Bird A: caw caw caw caw caw caw caw caw
Bird B: caw caw caw caw caw

F (0:59-1:07). Again the second crow shifts from his longer caaw to match the shorter caw of the first bird. Listen carefully and you'll hear how this sequence beings unmistakably with the second crow's longer caaw; what follows are two more of those long caaw notes, but simultaneously the first crow offers three shorter caw notes. On the next two notes, the two crows caw simultaneously, the second crow having now shortened the duration of his longer caaw to match the caw of the first crow. I think the last three caws are from the first crow, but I can't be sure.
Bird 1: caw caw caw caw caw caw caw
Bird 2: caaw caaw caaw caw caw

G (1:12-1:25). It's much easier to hear how the second crow matches the first in this sequence. First, there are three of the longer caaw notes from the second crow. Next, the first bird calls seven times, caw-caw-caw-caw-caw-caw-caw, followed immediately by the second bird adding three identical notes of its own, caw-caw-caw, the entire 10-caw sequence sounding as if it were one bird.
Bird 1: caw caw caw caw caw caw
Bird 2: caaw caaw caaw caw caw caw

Track 2-16: The songs of Li'l Brown two weeks earlier, on June 5, were still in the making. On June 17 he would be consistently singing the phrases A B D E F G I J, but on June 5 the sequence in these ten songs is more variable: A B N E F G, A K L E F G, A B N E F G, A B N E F G, A K L J F, A B N E F G, A B M N E F G J, A K L J F, A B N E F, A B L E F G. Notice that Li'l Brown will eventually jettison the . . . phrases K, L, M and N (not found in the song of his tutor, Ol'Blue), and he'll add D (copied from Ol'Blue) and I (source unknown). Try to hear the inconsistencies as you compare successive songs.

Track 2-17: Songs of an older bunting, Blue-2, at Quabbin Hill, just a half mile away from the Enfield Lookout. His first song is complete, consisting of Phrases A K T U H F V, with Phrases U and H making up the three distinctive buzzy phrases in the middle of the song. More typically, he stops the song after just one or two buzzy phrases, as he does with the four other songs here. A prairie warbler sings in the background, his rising buzzy song distinctive.
