SX50--spring on the rocks
4 months ago

Getting down to incubating eggs may be a bit slow at our cliffs this year due to an intruder female peregrine who was trying to win the affections of the male and to claim the eyrie (nesting site) for herself. She seems to have lost out in favor of the local female peregrine as the activity below suggests:

The female leans over to make a secure landing site for the male who signals he's on his way by flying around the area in a couple of loops and calling out. She also calls out and makes no effort to avoid the encounter.

He lands and clasps her wings and flaps to balance.

They make brief contact for 4-10 seconds.

He flies off.

She squawks briefly but stays put and stands up afterward as if nothing had happened.

This routine is apparently only partially for the fertilization of the eggs. It is very short in duration, it repeats several times a day for a couple of weeks and is part of the complex of behaviors that trigger the female to produce eggs, package them in shells, lay them in the eyrie and then start incubating them.

Thanks for looking.

Don
