4 UPTON, MAINE 1871 ping calls on the trunks of trees, which were auditable at a great distance in still weather: both sexes incubate. 9. Hylotomus pilcatus, said to be frequent though we did not see it. 10. Melanerpes erythrocephalus, took a fine female May 30; was probably a mere straggler. 11. Colaptes auratus, quite scarce; breeds 12. Trochilus colubris, quite frequent; breeds 13. Chaetura pelagia, common: do not think that it breeds in hollow trees as we found none away from the settlement. 14. Antrostomus vociferus, a single male sang every night near the hotel: is said to occur everywhere in the woods. 15. Chordeiles popetue, quite common breeding. The females for three nights (June 4th, 5th and 6th) when about to deposit their eggs, came in large numbers to a small patch of cultivated ground in front of the hotel where they moved about in the dusk with a strange awkward sidling motion, apparently picking up the fresh earth. So tame were they that if one was shot the others paid no attention, but continued feeding. The males kept high up in the air occasionally swooping down and uttering their strange cooing note. 16. Ceryle alcyon, freqent on the lake, a ♀ taken June 10 had not commenced to lay. 17. Tyrannus Carolinensis, rather scarce, saw them occasionally on the lake among the "stubs". 18. Sayornis fuscus, saw a few males.
