Watching Feathers Grow

The Peregrine chicks are feathering out in a big way. They currently have the “salt & pepper” look as they molt into juvenile plumage. All are now showing color on their faces and even a moustachial stripe. The chicks are not all at the same stage of molt – the first hatched chick is more advanced than the other two. His behavior is also slightly more advanced. He’s the one most likely to be standing close to the box opening and watching out for a parent flying in with food. All the chicks have been contending for food fairly evenly these days, although occasionally the first and third hatched chicks seem to sit out a meal. The second hatched chick, which we believe is a female, is the most aggressive. This morning she snatched a small meal from her father and proceeded to finish it all by herself. No one including Ares complained.

  2. What is the gender of each ( in birth/hatch order)

    Hints have implied, last year it was officially mentioned

    Thought tiercels were smaller than falcons

  3. Thank you again Matt for the wonderful pics and great information. I cannot believe how fast they are growing.

  4. They finally have hooked adult beaks , one is really pronounced, outgrowing their baby shaped beaks

    They are transforming fast

  5. Gee, in just days they are losing their down

    This morning it is quite noticeable, especially for one

  6. Just now, Comet is sitting up on the edge of the nest box, looking like he wants to fly. I tell him to get down, but he won’t listen.
