While audio detection devices always needs treating with caution (mine insists I already have Hummingbirds), I=E2=80=99ve now had a Haikubox detector running in my backyard for over 18 months, and it produces some interesting data on Junco detections. Glenn's date of May First looks to match last year's data, and if that pattern follows, we might really be trading Juncos for Hummingbirds in the next week or two.
(Image description: a three-year graph of song detections of Dark-eyed Junco. The data starts mid-2023 and the first rise each year is in October. Spring 2024 shows a distinct peak in early April, dropping to near-zero by the last week of the month. However, the data from late 2024 to early 2025 shows noticeably higher levels, and no significant drop yet).
