Note: table does not include nocturnal banding (owls) |
Banders-in-charge: Simon Duval, Gay Gruner
Censusers: Jean Demers, Frédéric Hareau, James Junda, Barbara MacDuff, Karen Nassi
Notes: Temperatures were more seasonal this week, and daily census counts were consistently between 18 and 20 species, except for a midweek spike to 28 species on April 6 and 25 on April 7. Sharp-shinned Hawk, Cooper's Hawk, Rock Pigeon, and Belted Kingfisher were observed for the first time this year, while we had our first spring observations of another seven species: Northern Goshawk, Mourning Dove, Northern Flicker, Eastern Phoebe, Brown Creeper, Golden-crowned Kinglet, and Chipping Sparrow.
Eastern Phoebes were observed on census four times this week, hopefully establishing a territory as in many previous years.

Although a number of new species arrived at MBO this week, the most abundant birds were very similar to week 1, with only Blue Jay dropping out of the top ten, replaced by Slate-colored Junco. Canada Goose and Red-winged Blackbird remained in the top two spots, which is typical for the second week of spring. Song Sparrow numbers were slightly higher than average for this early in spring, while American Crow and American Robin were a bit lower than usual, and Black-capped Chickadee right on the mark compared to previous years. Wood Duck and Mallard made the top ten for a second straight week, both with numbers a fair bit higher than in previous years.

Waterfowl sightings have already been nicely varied this spring, including this male Green-winged Teal doing his best to elude the photographer.
