Since the senior author published his article " Birds of Toronto, Ontario," 1 twelve years ago, there has been much change in con- ditions affecting bird-life near Toronto. The land birds have not been seriously affected. The ravines, especially those of the Don and Humber Rivers, form decided obstacles to the expansion of the city and still contain wooded tracts which provide shelter and food for many migrants.
