Show 64 MR. A. BOUCARD ON BIRDS FROM COSTA RICA. [Jan. 15, 205. MYIOBIUS SULPHUREIPYGIUS, Sclat. Two specimens, from Naranjo, April. 206. MYIOBIUS ERYTHRURUS, Cab. One specimen, from San Carlos, February. This seems to be a rare species. I wanted more specimens, and could only succeed in seeing another, which I could not shoot. 207. MITREPHORUS AURANTIIVENTRIS, Lawr. Several specimens, from La Laguna, February Naranjo, April, and Candelaria, May. I killed these in the forest at the altitude of 4000 to 8000 feet. They used to stay at the same place for a long time; they select a branch, and you see them there all day long. All the time they fly about catching insects, and returning to the same spot. I missed one of my specimens twice; notwithstanding, it came back to its favourite branch. There is no appreciable difference between the two sexes. I have also one specimen with the abdomen of the same colour as the throat and the breast; otherwise there is no appreciable difference. It was obtained at San Mateo, altitude 1000 feet. 208. EMPIDONAX FLAVESCENS, Lawr. Several specimens, from Naranjo, April. 209. CONTOPUS VIRENS, L. Several specimens, from Cartago, April. 210. MYIARCHUS CRINITUS, L. Native name " Traga mosca." Several specimens, from San Jose, January, and Cartago, April. Rather rare in Costa Rica. They used to perch on a selected branch of the trees edging the coffee-plantations, and remained there all day long catching the insects passing by. 211. MYIARCHUS PANAMENSIS, Lawr. Three specimens, from Punta Arenas, May. Killed on the mangle-trees near the river. 212. MYIARCHUS LAWRENCEI, Giraud. Myiarchus nigricapillus, Cab. Many specimens, from San Jose*, Cartago, and Naranjo, January to May. Native name " Tonto vivo." 213. MYIARCHUS CINERASCENS, Lawr. Two specimens, from Punta Arenas, May. Killed at the end of the sandy point near the town. 214. TYRANNUS MELANCHOLICUS, Vieill. Many specimens, from San Jose, January to May. Common everywhere, especially on the trees surrounding the coffee-plantations. |
