I would agree on the first broods being out and fly-worthy by now, most likely. And second or later broods are probably generally less successful, at least in such birds as Red-winged Blackbirds that actually do NOT raise two broods around here, although they may try-try-again as many as 4 times. Are Eastern Meadowlarks known to fledge and rear two broods? I wonder. In any case, now is much less likely to have an impact on successful, likely-to-survive young birds.
Out my way, near Freeville, massive cutting of fields happened in 2nd week of June and I am pretty sure that redwings lost many broods, directly to mowing or indirectly to the hawks, crows and others (even Killdeer?) who immediately recruited to the fields. It was not an early year for redwing nesting, from what I could tell, and the parents were going in and out of specific sites still when the mowing happened. I had not seen any fledglings. So not only is there not single magic date, that date changes from year to year...
