Ontario

espite the relatively mild winter in much of Ontario, March and April remained cooler than normal overall and fairly quiet from the perspective of rarities.Spring migration appeared delayed at many locales, with pushes of returning migrants occurring later than usual.However, as is often the case, there were many exceptions that set local record-early dates, if only by a few days.Cold and wet conditions in March and April changed to warmer and more seasonal conditions in May, although that had the consequence for birders in allowing migrants to over-fly many traditional birding spots.Fallouts were noted at the end of April, but few were noted afterwards.Highlights included White-faced Ibis, Rock Wren, Bell's Vireo, and two colorful buntings, a Lazuli Bunting and a Painted Bunting, which enthused those who were able to see them.Abbreviations: N.PH.(Niagara Peninsula Hawkwatch); Pelee (Point Pelee N.P, Essex); P E.
