Document Summary

Connected in time to the growing season. Mixed forest (mixedwood forest)- once typical of north facing slopes, now increasingly widespread. Willows in low moist areas and along streams (often with alder) Sandhills (with jack pine) sandy uplands, once dunes. Rural settings- farmyards often rich in animal life. Suburban- may offer many food, warmth, and shelter resources. Industrial- may also provide more habitat than you might think. Lots of overlap among the faunas of the various sorts of environment- but a few specialists in some environments. Some birds are year-round residents with relatively stable populations. Some residents, such as red-breasted nuthatches, are more prone to population fluctuations. Snowy owls are found in open, usually cropland areas, and they feed mainly on rodents. Northern shrike sit high in trees and also feed largely on rodents. Synanthropic introduced species, always associated with people: house sparrow, rock pigeon.
