Birdsong by the Seasons: A Year of Listening to Birds, Volume 1
Poast new message in this thread
Date: April 10th, 2014 2:07 PM Author: bright misanthropic macaca 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 |
Date: April 11th, 2014 2:22 PM Author: bright misanthropic macaca 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 |

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 |

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 |

Date: June 9th, 2014 4:14 PM Author: bright misanthropic macaca Track 2-14: Five songs of Ol' Blue, the bird who was two years or older at the Enfield Lookout, Quabbin Park. Feel the rhythm, the fire fire where where heeerre my my run run run faster faster safe safe pheewww, the paired phrases at the beginning followed by the single up-slurred buzzy heeerre, then more paired (or triple phrases), ending with the pheewww buzzy phrase on the end. Or try to follow along by simply counting phrases: 2 2 buzz 2 3 2 2 buzz. In the background are the songs of Li'l Brown, the yearling who learned almost the entire song of Ol' Blue.

Date: August 20th, 2014 11:43 PM Author: bright misanthropic macaca Track 2-15: Ten songs of Li'l Brown, recorded June 17, by which time he had copied most of the song of Ol'Blue. The song of Ol'Blue contains the phrases A B C D E F G H, the song of Li'l Brown now A B D E F G I J, omitting the two buzzy phrases (C and H) and adding two other phrases (I J) to the end. I confess I was frustrated trying to record the songs of Li'l Brown, as he seemed to stay so distant, so I played one of his songs to him; he then flew to a tree nearby and sang at twice the usual rate, chipping between songs.

Date: August 23rd, 2014 2:08 PM Author: bright misanthropic macaca 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. (http://www.autoadmit.com/thread.php?thread_id=2540401&forum_id=2/#26190498) |

Date: February 4th, 2015 3:22 PM Author: bright misanthropic macaca 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.

Date: February 19th, 2015 4:33 PM Author: bright misanthropic macaca Subject: Track 2-18: Songs of the other older bunting, Blue-1, at Quabbin Hill. His first song is complete, with Phrases P K L J Q R S. He is somewhat "excited" in this sequence, his second song being a double song (P K L J Q S R K P K L J Q R), a couple of the phrases (S R K) out of order between the songs. Other songs are incomplete, leaving Phrase S or both R and S off the end. (http://www.autoadmit.com/thread.php?thread_id=2540401&forum_id=2/#27350616) |

Date: March 2nd, 2015 2:43 PM Author: bright misanthropic macaca Track 2-19: Sample songs from the one yearling who settled next to adult male Blue-1 on Quabbin Hill and adopted his song almost perfectly, singing the same sequence of song phrases: P K L J Q R S (http://www.autoadmit.com/thread.php?thread_id=2540401&forum_id=2/#27417085) |

Date: March 21st, 2015 5:07 PM Author: bright misanthropic macaca Track 2-20: When a yearling returns from his first migration, he resumes work on getting the right song for the neighborhood where he will settle. As illustrated here, he can ramble on and on, revealing that he has memorized far more song phrases than he could possibly use in the song that he eventually perfects. In roughly the first 16 seconds here, this bunting sings 16 different phrases, in the following sequence: L J Q R d W V H S R K X K L J Q R S H Y Z K X C J Q R S H J a b J Q R L J. Many of these phrases are sung by his adult neighbors, and the underlined sequence already is almost a complete match for the songs of the adult with whom this yearling is battling for a territory (Blue-1, whose standard song is P K L J Q R S).

Date: June 3rd, 2015 2:21 PM Author: bright misanthropic macaca Track 2-33: Through the binoculars, it is clear that down below in the marsh the young eastern kingbirds open and close their bills as if they are calling, but with the unaided ear we hear nothing. With the parabolic microphone aimed at them and the gain turned high, their sharp tzeet calls rise out of the background noise. The kingbirds are flycatchers, which don't learn their songs, and the calls of young birds are often already similar to the sounds that adults will use as songs throughout their lives.

Date: June 25th, 2015 12:54 PM Author: bright misanthropic macaca Track 2-34: Yes, it *is* a young warbling vireo overhead. Hear his distinctive call and then the unmistakable attempts at his song. The overall rhythm and quality are already surprisingly good, though the details are unformed. Successive songs are never the same, with some short and some long, the component notes and their arrangements all uncertain. At times he hurries from one song to the next, too, blurting out hastily all that he knows. (http://www.autoadmit.com/thread.php?thread_id=2540401&forum_id=2/#28197777) |
