<. For example, last year, Drumlin Farm’s team won the prized Hathaway Cup for raising the most money ($34,820) and a dedicated individual on that team was the statewide top fundraiser with $15,309 raised. The conservation dollars that can be raised can be significant.
Catibirds dine on fruits and berries and are year-round frequent visitors for the feast we provide, including blueberry, Juneberry, winterberry, and holly berry. From Cornell, “The Gray Catbird belongs to the genus Dumetella, which means “small thicket.” And that’s exactly where you should go look for this little skulker.” Love the beautiful shade of blue of Catbird eggs! Gray catbirds belong to the ‘Dumetella’ genus, which means “small thicket”, which is where this bird can be found hiding. This program is supported in part by a grant from the Gloucester Cultural Council, a local agency which is supported by the Massachusetts Cultural Council, a state agency. Back in 2004, I thought it would be fun to see how many species we could find without leaving Cape Ann (Gloucester, Rockport, Essex and Manchester). Mass Audubon’s Ipswich River Wildlife Sanctuary is offering a free bird walk at Eastern Point Wildlife Sanctuary in Gloucester on Wednesday, May 8 from 9:00-11:00 a.m. Join Ipswich River Wildlife Sanctuary Director Amy Weidensaul for a walk that will traverse beautiful coastline and wetlands as well as forested habitat. Gray Catbirds sometimes destroy eggs and nestlings of woodland species including Eastern Wood-Pewee, Chipping Sparrow, and Song Sparrow. Free! Love the beautiful shade of blue of Catbird eggs! You can either pledge an amount per bird ($1/species @ 132 species = $132) or just pledge a set amount. This year Bird-a-thon takes place May 11-12 and consists of having as much birding fun as we can stand in the 24 hours between 6:00 PM Friday until 6:00 PM Saturday. h�bbd```b``���A$�f�u���,+�j>�ɩ`q~�*�I�#��m`�:�^��f�k

Gray Catbird Eggs image courtesy Cornell Lab of Ornithology The nests of this species often have the eggs of Brown-headed cowbirds laid in them. Sealy (1994) reported 2 separate obser-vations of egg predation by catbirds on eastern kingbird (Tyrannus tyrannus) eggs in Manitoba. The female may sing the quiet song back to her mate.
