The Global Big Day bird count took place on May 10, 2025 and Haikuboxes were listening! It is always interesting to take a snapshot of the birds identified by Haikuboxes across the world, and this event gave us the opportunity to listen to birds during the peak of spring migration.
There were over 2,700 Haikuboxes online which collectively identified over 600 bird species and created over 6.7 million bird song and call recordings in just one day. During the mid-February Great Backyard Bird Count, Haikuboxes gathered fewer than half the number of recordings, just 3.3 million in one day.
The top bird species identified included House Sparrow (about 650 k recordings), Northern Cardinal (523 k recordings), House Finch (518 k recordings), American Robin (344 k recordings), Carolina Wren (306 k recordings). Together, they accounted for almost 35% of all birds recorded on this day.
The diversity of birds identified was on display and included newly arrived migrating birds like the Chipping Sparrow (47 k recordings from over 1,100 Haikubox sites), Baltimore Oriole (25 k recordings from over 870 Haikubox sites), and the American Redstart (12 k recordings from over 450 Haikubox sites).
Some other favorite birds included Cape May Warblers (identified over 8,000 times at 590 Haikubox sites), Tennessee Warbler (identified over 62,000 times at more than 560 sites), and California Towhee (identified over 149,000 times at more than 230 sites).
Other cool birds recorded included the Indigo Bunting (identified almost 10,000 times at over 300 Haikubox sites), Scarlet Tanager (identified almost 11,000 times at over 800 Haikubox sites), and Painted Bunting (identified almost 12,000 times at over 120 Haikubox sites).
See you next year!
