Détails de l'observation
Conservative estimate. Upon my arrival on the property and just a short distance from the gate, I counted 287 swallows perched on the telephone lines on the right side of the road. (Multiple photos show all 4 species present, but I couldn't get all of them in one frame.) At the same time, dozens were swooping in and out over the brush and others were flying back and forth over the water in the drainage canal. Additionally, at least 15-20 more were gliding over the lake.
