13 November 2021
It’s been a warm week in November for crows and insects with lows above freezing and highs in the mid to upper 60s.
Since I last reported on Pittsburgh’s winter crows they’ve changed their flight path and staging areas. Prior to 2 November they staged near the border of North Oakland and Shadyside but that evening they refused to fly over my neighborhood and haven’t done so since. I imagine they wore out their welcome and were encouraged to leave.
Frustrated that I could not see them from home I searched by car late Monday afternoon. There were no crows staging in the Upper Hill, Polish Hill, the Strip District, or near Trees Hall though I found a few hundred at Oak Hill west of Carlow. As I drove back from the Strip District I found a steady stream of crows flying toward the Cathedral of Learning — from where? — carefully avoiding the airspace above North Oakland and west Shadyside.
I chased them down to Frick Fine Arts where thousands were pouring in from every direction. They swirled in the trees near the Mary Schenley Memorial Fountain and perched on the roof of Posvar Hall. In the top photo the fountain’s female statue appears to be holding up her arm to ward off the crows but in fact she is plucking a lyre and singing A Song to Nature for Pan, the reclining male figure, frozen in bronze since 1918.
Of course the crows would love to roost near the fountain. It has everything they’re looking for. Mature trees, night lights and the white noise of splashing water. But there are too many of them. Those who can’t find a spot fly over Central Oakland in the dark, scrambling for a place to sleep.
Meanwhile the week’s warmth brought out a last hurrah of insects including a Virginian tiger moth (Spilosoma virginica) or yellow woolly bear in Volant, PA …
… and a leaf-footed bug outside my window, probably a magnolia leaf-footed bug (Leptoglossus fulvicornis). Last year’s leaf-footed visitor was eight days earlier in November. I think I know why they show up.
Leaf-footed bugs overwinter in leaf litter and are undoubtedly rousted out of their haven when the leaf blowers show up. Shortly before this bug appeared on our window, the 4-man leaf-blower crew at Ascension Church was in the final noisy throes of blowing and vacuuming a huge pile of leaves. I imagine the bug took refuge on our window while he figured out a new safe place to sleep away the winter.
He has something in common with the crows.
