觀察細節
**very rare in spring -- first identified by J. Dowdell at 1430. An overall stocky and warm-colored swallow with squared tail, viewed in direct comparison to two TRES; studied in good light though generally flying >50ft above the ground during my observations. Tawny throat, forehead and cheek; gray nape; pale flanks that did not contrast with underparts; tawny rump. The latter two field marks state a good case for this individual belonging to P.f. pallida. Photos show p9 retained.
