Back in May of this year I had an opportunity to observe a Brown Creeper nest. It was located along the east dyke trail at Reifel in a vulnerable spot, so its existence was not common knowledge. The nest was built behind a large piece of loose bark. While there was some routine activity during the incubation period, it definitely picked up once the chicks hatched.
Here you can see one of the adults arriving with food and looking into the nest making its presence known.
Then the other exiting the nesting cavity,
… and heading up the tree before flying off.
Then the arriving adult,
… enters the nest with the food delivery for the chicks.
Keeping track of the days I had hoped to be around to catch the fledglings leaving the nest. Unfortunately I missed that moment,
… but did catch this shot of one of the adults at the nesting tree after the young had left. It was a great few weeks watching all of this unfold.
