Nearly a month ago, I watched a Black-capped Chickadee couple excavate a cavity nest in a snag. The exercise went on for quite a few days. There was no guarantee that they would occupy it for they tend to dig several cavities before deciding which one can be their ideal home. Then activity stopped and nothing more was seen until today.
I saw one chickadee (the female) vanish into the cavity. Soon, the male arrived with something in his bill. He vanished into the cavity and in 12 seconds returned with an empty bill. I will keep watching it in the hopes that chicks may be seen.
After the female has entered, the male arrives with food.
And in 12 seconds he is off for more food. We may see an average of 7 chicks.
