To better follow along during migration and compare to previous years, the number of birds banded in spring 2025 are graphed every banding day. 2025 is the number of birds banded each banding day. 2024 is the number of birds banded on the same date in spring 2024. And Average is the average number of birds banded on the same date based on every previous spring season. These numbers do not take effort into account and are for general comparisons.
To better follow along during migration and compare to previous years, the number of birds banded in spring 2025 are summed every banding day. 2025 is the cumulative number of birds banded this spring by date. 2024 is the cumulative number of birds banded in spring 2024 on the same date.
Species numbers are added to daily during the season, with the top ten changing as the season progresses. 2025 is the current number of birds banded thus far in the season. 2024 is the total number of that species banded in spring 2024. And Average is the average number of that species banded during the spring season. These numbers do not take effort into account and are for general comparisons. For a breakdown of all species, high records, first and last capture, and highest capture date, click the 2025 Spring Weekly Banding Totals at the top of the page.
Return birds are those that are captured and already have a band, but were not banded in the current season (they were banded in a previous season or year and are returning). This table displays species captured this season with return individuals, the number of individuals, and the season/year those individuals were originally banded in.
