78 THE CONDOR Vor,. XII let), only two were seen. Inca Doves, Mexican Ground Doves, White-winged Doves and Mourning Doves were all abundant except the first mentioned, and for the most part frequenting the open roads and fields. The only pigeon seen was the Red-billed (Columba fiaviroslris). On April 29 I found one incubating a single egg on a frail platform of twigs in a clump of bushes. Mocking Birds (Mimus polyglollos leucoplerus) were not uncommon but a peculiar thing was that 'they did not do any singing, tho I watcht them for some time on different occasions. Bronzed Cowbirds ( Tangavius aeneus aeneus), Groove-billed Anis ( Crolophaga sulciroslris) and Brewer Blackbirds (15?uphagus cyanocephalus) occupied every field where there was any stock. Colima Ground Sparrows Airnophila acuminala) and Mexican Goldfinches (Aslragalinus psallria mexicanus) were mainly evident as roadside birds. A very rare and shy bird, two seen, was the Rufous Cuckoo (Piaya rnexicana), a slightly larger bird than ours and very much longer tailed. Wrens were noticeably absent, the only ones noted being the Happy Wren (Pheugopedius felix) and an unidentified species. Our familiar friend the West- ern Gnat-catcher (Polioplila caerula obscura was present tho not at all common. Scarlet-headed Orioles (Icterz?s puslulalus) were numerous, and a few individuals of Painted, Redstarts (Setep/za?a picta), Hepatic Tanagers (Pira?tga /zepatica) and Arizona Hooded Orioles (Icierus cucullalus ?elsoni) were observed. The natives had many Tres Marias Cardinals (Cardinalis cardinalis mariae) in cages, which they got from the Tres Marias Islands some fifty miles off the coast. We were dis- appointed in not finding hummingbirds present in numbers and species. Only the Rufous (Selasp/lo?'us ruftts) and another of undetermined species were seen. Mr. Osburn secured one Xantus Becard (PlatypsarD albiventris), the only one seen. White-rumpt Swallows (Taclzycinela albilinea) were nesting 'in fence posts May 10. The flycatchers were very abundant and well represented by the Derby Fly- catcher (,t'ita?zgus derbian?ts) the largest and noisiest and particularly haunting the streams, Cassin Kingbird (T. yrannus vociferans), Giraud Flycatcher Al. yozeletes similis superciliosus), Ash-throated Flycatcher ( ?V/.yiarclzus ciJterascens) Vermilion Flycatcher ( P. yroceplmlus rubineus mexicanus) and Least Flycatcher ( Empidonax rainlinus) the latter being rare. In passing Nativtdad Island, what I took to be Sooty and Black-vented Shear- waters, Brandt and Farallone Cormorants were numerous. One Farallone Cor- mor?mt was observed at San Bias. Other birds seen, not mentioned above, were Douglas Quail (Lop/?orlyx do?t?lasi), Purple Gallinule (Io?wrnis martinica), Cuerna- vaca House Finch (Carpodacus mexicanus r/wdocolpus), Lincoln Sparrow (Agrelospiza- lincolni) and Pigmy Owl, (Glaucidium p/zalae?toides). Many other birds were seen that were not identified, the most prominent among which was a large black tree duck, another species of Mexican duck, a large white-headed hawk with a rufous colored body, and a large owl. The Tierra Caliente or Hot Lands offer much in the way of collecting, but also considerable hardship in so doing. If collecting eggs, the trees selected by the birds for a nesting site, if not the slippery and tall cocoanut trees or the thorn trees, are very large around the base with the first limbs starting at some distance from the ground; besides the enervating climate makes about one such tree climbed, a day's work. The swamps are well nigh impenetrable, tho one does not have to watch out for venomous snakes. The only snakes I saw were sea-snakes which remain well out to sea. Woodticks are especially numerous and a sort of a jigger, called by the natives Wenas, are very rap.acious. If allowed to get ?under the skin they frequently make very painful,and troublesome sores, and if out in the 'brush much it is impossible to keep them from boring into the skin. A very small gnat
