We present new distribution information for 19 species of Costa Rican birds. Thirteen species show changes in altitudinal distribution, 9 are recorded at higher elevations such as Egretta rufescens (Gmelin, 1789), Heliomaster constantii (Delattre, 1843), Myiozetetes cayanensis (Linnaeus, 1766), and Lonchura malacca (Linnaeus, 1766), and 4 are recorded at lower elevations, Panterpe insignis Cabanis & Heine, 1860, Empidonax albigularis Sclater & Salvin, 1859, Sayornis nigricans (Swainson, 1827), and Dacnis venusta (Lawrence, 1862). We recorded 2 forest understory species, Geotrygon montana (Linnaeus, 1758), and Grallaria guatimalensis Prévost & Des Murs, 1842, inside the area of the county with the most urban development. Finally, Saltator grossus (Linnaeus, 1766), which was restricted to Caribbean forest, was recorded at the South Pacific rainforest for the first time.
