The following is an extract from Dr. Wetmore’s interesting description of the Gray Kingbird in the bulletin, “Birds of Porto Rico,” used with the permission of the author: “The gray kingbird has the reputation among the country people of being the earliest riser among birds. In the daytime it scatters along the slopes and through the fields to feed, but at nightfall gathers in small parties along streams to roost in the bamboos or in the mangroves surrounding the lagoons. The nesting season extends from April to July and during the latter month young are abundant. At all times very pugnacious, pursuing blackbirds, hawks, and other birds, they now become doubly so, resenting all intrusions in their neighborhood. Occasionally they were seen standing on open perches during showers with outspread trembling wings, evidently enjoying the downpour. “A few facts regarding the insect food of this kingbird were learned from field observation. Birds were twice observed eating the caterpillars of a large sphinx moth. These were beaten on a limb, and then the juices were extracted by working the body through the bill, while only the skin was discarded. Their services in eating these and other caterpillars were recognized.” |
