Butterfly Time!
The woods are becoming quieter and quieter as each day passes. For most birds, the breeding period is long gone and the nesting time will soon close. As the fledgings grow and gain their independence, the songbirds' northern sojourn will come to an end no later than late September. Yet many warblers will begin their "fall" migratory trip to the tropics toward the end of July and in August.
For breeding fireworks, however, there is always the American goldfinch, the last songbird to breed, to entertain us birders. If you have the time and can hang out with a bunch of goldfinches for a while in mid-August, watch for their incredible aeronautic courtship displays.
And what about the butterflies? They're in full swing in northern fields and pastures. Even in the forests, a few can be found. I planted a butterfly bush (buddliea) this year in a gigantic pot on my deck and enjoy having them so close by. Monarda is another perennial that's worth planting if you want more butterflies in your yard.
It mystifies me. Last year the milkweed, a favorite food of Monarch butterflies, bloomed in mid-June and this year it's blooming now, in mid-July. I've tried to recall what makes this summer's weather different than last. One huge difference has been this summer's very cool nights, with many temps in the 50s, occasionally dropping to the high 40s. The nighttime chill has retarded the growth of almost every vegetable except for the lettuces.
Besides delaying their major food supply, butterflies are bothered by cold as well, and there do seem to be fewer of them now. If the weather warms up as expected (the long-range forecast says a heat wave is coming late next week), I'm going to watch to see if more butterflies appear.
