Spring Migration

Monthly Summaries of Spring Migrants

May

May is the month dear to the hearts of most birders, since it is possible to see more species at the height of migration (about mid-May) than at any other time of year. Now many of the long-distance, land bird migrants arrive, many from Central and South America. It is interesting that these migrants from afar arrive on more predictable dates each year than do those spending the winter closer to Ontario.

Weather plays an important role in the numbers of a species one is likely to see. On rare occasions there will be a "grounding" of migrants due to inclement weather, and it is then that astounding numbers of certain species will descend on Point Pelee. This phenomena, however, is the exception, rather than the rule.

Most of the waterfowl migration is over by early to mid-May and many of the April land bird migrants as well have already passed through.
