Monthly Summaries of Spring Migrants
Again, like March, the amount of migration in April is dependent on the weather. Usually once or twice during the month, however, a warm spell will occur, and it is then that there will be a wave of migrants including the first insectivorous species. During April, many of Pelee's winter visitors such as the common merganser, rough-legged hawk, short-eared owl (rare), hairy woodpecker, common redpoll and American tree sparrow will be seen for the last time.
Black-crowned Night Heron
American Golden Plover*
Louisiana Waterthrush (rare)
With an exceptional warm front in the last few days of April a surge of typical May migrants may appear. If, however, the weather is more-or-less normal, only the following are likely to be new arrivals in the last ten days of the month.
Gray Catbird Virginia Rail
Henslow's Sparrow (rare)
Black-throated Green Warbler
In mid-April, horned grebe, gadwall, green-winged and blue-winged teal, American wigeon, northern shoveler, lesser scaup, American coot, tree Swallow and both kinglet species are likely to be encountered in exceptional numbers.
