It’s difficult to identify individual Peregrine Falcons while observing them in the wild. If anyone has good advice on individual identification, I would greatly appreciate it.

Back in the field after two weeks away. Life outside the falcon field has been busy lately.

Instead of incubating, the pair began mating.

The incubating female has left the nest and started mating on the cliff.
A third Peregrine is circling above, but its identity is still unknown.

As the seasons change, the rain continues. I’m worried about the Peregrines during incubation.

There is a chick! Hatched in the last couple of hours I think, still a bit wet.
This was the first time Azina left the box since 6:30pm yesterday. Still no sign of Tom...

Today’s observation was rather uneventful and felt a bit unsatisfying. But for the Peregrines, that may be the best outcome.

As Japan shifts from winter to spring, frequent rain is keeping me out of the field. ☔️

Incubation is underway, but unfortunately the clutch size cannot be confirmed.

Incubation has begun, and changes in their territorial defense behavior are becoming apparent.

Back to observing Peregrine Falcons after a week — it looks like incubation has begun.

I turned one of my photos into a design and made badges…

The Peregrine Falcon was incredibly fast today — motion lines added to show its speed.

Today’s observation also recorded several territorial intrusions by a third individual.

A biomechanist reportedly measured the acceleration generated by Peregrine Falcons during vertical ascent.

The accelerometer reportedly maxed out at over 25 G.🦅💨💨💨
