In late summer season, a younger Bald Eagle leaves the nest and units out by itself for the primary time. It’s the end result of practically a yr’s work by the dad and mom.
Let’s recap the way it might need gone: female and male meet up in late fall, construct a brand new nest or add sticks to their outdated one over the winter – and by March, often have two eggs. The feminine incubates for a month-and-a-bit, with the male taking an occasional flip. The end result? A few tiny, three-ounce chicks.
The adults then take to searching fish and different prey, tearing it into bite-sized chunks for the rising kids – which acquire a pound in weight each 4 or 5 days.
At eight weeks, they’re all brown and as heavy because the adults – 10 to 14 kilos.
Two weeks later, they make their first quick, clumsy flights. Nevertheless it’ll take one other 10 weeks of follow flights and provisioning by the adults earlier than the younger birds are able to strike out on their very own.
And once they do, they strike out in grand vogue, wandering over the continent for maybe 1000’s of miles, till 4 years after hatching, they’ve their full grownup plumage. Solely then may they search a mate and construct their very own nest. [Bald Eagle call, http://macaulaylibrary.org/audio/137879, 0.18-.21]
