Hate to burst your happy bubble but the cowbird chick will be bigger than the phoebe chicks and will push the other chicks from the nest then the phoebe (or other song birds) parents will have that one chick to raise and it will do very well - no competition.View attachment 4120419
Mama Phoebe laid her first egg! The Eastern Phoebe normally lays 4-5 eggs (but sometimes 2-6), and brown headed cowbirds, which are obligate brood parasites, often lay an egg or 2 in a Phoebe nest so if that happens, how cool! Would be fun to observe. Incubation is about 16 days and they typically raise 2 broods during the breeding season.
Happy mother's day, little Phoebe! Good luck with your clutch!
If I see cow bird eggs in a song bird nest I get rid of it.
They are not like chooks in that the chicks from many mamas can be raised together - unfortunately.
Cow birds here are an introduced species. Have to say though it was fun seeing my chooks chase after them when they were picking apart the horse poop the other day! Not that cow birds were so very worried seeing as how they can fly and the chooks not so much!
