Diglossa Humeralis
The chickadee is a very common bird both in the field and in the city, but it can be difficult to observe because it remains most of the time hidden inside the foliage of trees and shrubs. His movements are fast and every now and then he changes places; this makes their detailed observation even more difficult. At times it peers out of the foliage of a flowering shrub or makes quick flights between isolated bushes, offering a brief opportunity to appreciate its dark plumage.
