New paper shows 26% decline in Vancouver's breeding birds since 1997
|
Hi all,
New data suggests that Metro Vancouver's bird populations have declined by 26% between 1997--2020. Some species have declined a lot, like American Robins and Barn Swallows, while others have increased, such as Black-capped and Chestnut-backed Chickadees.?
To see all the trends for each species based on breeding bird counts, see Figure 2 from the paper that colleagues and I just published:
(it's free to read).
Good birding,
