Red-breasted Mergansers are the last merganser species to migrate through our area. Both sexes always appear to have a shaggy "hair style". Unlike most other waterfowl , mergansers consume fish, about 15-20 per day. The more-colorful male is on the left. (Wolf. Oesterreich, 4/7/23)
A total of 113 avian species (plus 3 sp. & 1 hybrid) was recorded this month, ranking this month as the 9th highest April among 26 years of records. April 2022 with 138 species remains as the highest April, while April 1998 with 61 species is the lowest. This total is 35 species more than last month and 25 less than April 2022.
Listed below, following the species’ names, are the date(s) of sighting(s), plus the occasional miscellaneous information regarding numbers, gender (♂=male, ♀=female), age (im=immature, ju=juvenile, bp=breeding plumage, ad=adult, nb=non-breeding), color phase (b=blue, w=white), and location (BY=back yard, FY=front yard). The order follows the 63rd Supplement (2022) to the American Ornithologists’ Union Check-list of North American Birds and the 22nd Supplement to the 7th Edition (1998).
