On June 11, 2024 I took a kayak trip, starting at 5:30 a.m. from the canoe launch at Redwing Bay in Needham, Massachusetts, and traveling slowly upstream for about an hour. This recording captures the journey upstream and the journey back.
Many of the Baltimore Oriole nests at Charles River Peninsula hang over the river so a kayak is the best way to locate the nests and record the songs of the orioles on-territory. By June 11, overall Baltimore oriole song had passed its peak but there was still plenty to hear, which I’ve tried to indicate in the time-line below, as well as some hints about the origin of the some of the prominent bird noises on the recording.
Regrettably, an airplane passes overhead with some regularity. Rather than edit these moments out, I’ve decided to preserve a sense of the soundscape as it is, at the possible expense of maximum relaxation potential. Indeed, starting around the 1 hr, 30 minute mark, this recording becomes a document of overall environment noisiness, birds included.
1:32 Baltimore Oriole (BAOR) nesting female immediately followed by her partner whose song (sung by multiple birds) I’ve labeled “BAOR 01.”
01:53 BAOR 01 (obscured by red-winged blackbird)
02:48 First appearance of eastern Wood-pewee (multiple birds will be heard throughout)
03:17 BAOR three note vocalization in distance, probably female.

12:23 First appearance of male orchard oriole. There were three males at the Charles River Peninsula in 2024 and they all sang approximately the same song.
12:39 BAOR 20, which I’ve come to suspect might actually be the song of a female orchard oriole. I was never able to get visual confirmation, but this song was often associated with the male OROR song.
14:29 BAOR 08. It is not clear if this male successfully mated, but it did have one imitator (heard at 1:39:20).
