观察细节
seemed more abundant than white breasted. many vocalizing frequently up high. including audio recordings of one individual that made very long and loud vocalizations, not two notes but calls that lasted even 10 notes for up to 5 seconds, never heard them make that kind of call before. interestingly they also made that kind of call when the other birds seemd agitated- the chickadees and kinglets were very noisy while there was just a lot of movement in the canopy overall. don't know the cause of all that sudden spike in activity, but I did get some good audio recordings of those birds vocalizing. at least 3, including 1 that was seen up high briefly (very cute!) and all the rest heard only
