Now, during the first few weeks of March this year, early blooming trees and birds provide interesting opportunities to observe their intricate relationships. Watch tree tops of Winged Elm and Red Maple to see theirconsistent stages of seasonal growth and bird use.
These, and other early bloomers, may attract several winter resident bird species by providing a unique food supply at a critical time of nutrient need. Leaf buds and blossoms of the Winged Elm may be seen being consumed in concert by Chickadees, Tufted Titmouse, Kinglets, Pine Warblers, Cedar
Waxwings and others, beginning with first bud-swell.
With blossoms opening, pollen enters the relationship. Should air movements be limited, pollen exchange within tree tops and between different trees happens, assisted by both insects and birds.
