Autumn and Gracie, do either of you have any more black bird info??? I'm looking for things like their normal behavior, mating behavior, habitat, diet, size and wieght, flocks (how big they usually are), and other things like that.
I found this at: http://www.allaboutbirds.org/guide/Red-winged_blackbird/id And I think it will help us....
Size and shape-A stocky, broad-shouldered blackbird with a slender, conical bill and a medium-length tail. Red-winged Blackbirds often show a hump-backed silhouette while perched; males often sit with tail slightly flared.
Behavior-Male Red-winged Blackbirds do everything they can to get noticed, sitting on high perches and belting out their conk-la-ree! song all day long. Females stay lower, skulking through vegetation for food and quietly weaving together their remarkable nests. In winter Red-winged Blackbirds gather in huge flocks to eat grains with other blackbird species and starlings.
Flock-Red-winged Blackbirds roost in flocks in all months of the year. In summer small numbers roost in the wetlands where the birds breed. Winter flocks can be congregations of several million birds, including other blackbird species and starlings. Each morning the roosts spread out, traveling as far as 50 miles to feed, then re-forming at night.
Other facts-Different populations and subspecies of Red-winged Blackbirds vary markedly in size and proportions. An experiment was conducted that moved nestlings between populations and found that the chicks grew up to resemble their foster parents. This study indicated that much of the difference seen between populations is the result of different environments rather than different genetic makeups. Male Red-winged Blackbirds fiercely defend their territories during the breeding season, spending more than a quarter of daylight hours in territory defense. He chases other males out of the territory and attacks nest predators, sometimes going after much larger animals, including horses and people.
