Observation details

Noticed a larger dark red bird in a goldfinch flock bouncing above the treetops by the quail building. I tried to get on the bird just as the flock dipped below the treeline, but then I started hearing the characteristic JIP JIP JIP call notes in addition to the goldfinch calls. Luckily dropped my bins and started recording just as the flock popped back above the nearest treeline and was momentarily overhead before heading back out of sight. Edit 12/15/25 to add more discussion on type ID: I'm still pretty new to interpreting RECR spectrograms, but after a look in the finch guide I'm labeling as type 1. Very vertical spec with a sharp downward ending; much sharper slope than seen in type 2. Lacking "lightning bolt" shape seen in type 3. Peak landed between 4 and 5kHz, whereas type 12 should land closer to 6kHz. Type 2, type 3, and type 12 "should" be more likely here according to Finch Research Network occurrence/irruption maps, although these things tend to pop up wherever it seems. Appears to be only the 2nd or 3rd record in MD east of Garrett with audio (on ebird at least). Others in Baltimore in 2018 and one reported in Harford this past November.
