Quick Looks at Size and Behavior

Maybe you’ve noticed that after watching warblers for a while, sparrows look huge. Gloria (@Lucent508) captured them side by side.

On Day 25 at the peregrine nest at Charing Cross Hospital in London (Fulham and Barnes), one of the chicks explored the nestbox ramp. He stumbled on the last step but enjoyed the outing nonetheless (the stumble is last photo though it actually happened first). At one point his mother looked at him as if to say, “Are you OK out there?”

Even though they are not “persons,” falconcams give us insight into the individual personalities of the peregrines on camera. This year the new unbanded female at the Wakefield Cathedral Peregrines nest (@WfldPeregrines) in Yorkshire, England has a habit never observed in the previous female: “Our previous female would never stay in the nest whilst the male fed the chicks.”

In the video below the female watches the male feed the chick. Sometimes he passes her a morsel of food which she swallows … or she feeds it to the chick. It’s not often that you see two peregrine parents feeding one chick.
