Weather in April can be described in only one way: changeable. It can turn from spring to summer to winter in the matter of hours, making it difficult to know how to dress any given day – you may need a hat and gloves in the morning, then be wearing shorts in the afternoon. Even the weather toward the end of the month can be variable. Last Thursday (April 27th) Ottawa’s temperature reached a sunny, humid high of 26°C; yesterday (April 30th) the rain clouds moved in and temperatures barely reached 5°C.
Migrants have been returning in large numbers despite the inconstant weather. On Friday I woke up to see two White-crowned Sparrows on my backyard, and they were there again Sunday morning. This was a year bird for me, and the earliest date I’ve recorded them in my yard; normally they arrive during the first week of May, with my previous early date being May 4th.
