The common grasshopper warbler or just grasshopper warbler (Locustella naevia) is a species of Old World warbler in the genus Locustella. It breeds across much of temperate Europe and the western Palearctic. It is migratory, wintering across northern tropical Africa just south of the Sahara, and also locally in India. This small passerine bird is found in dense grassland vegetation, often close to water, and usually with a few small scattered shrubs. It is a medium-sized warbler about 13 cm (5 in) long. The adult has a streaked brown back and whitish grey underparts which are unstreaked except on the undertail coverts. Wikipedia →

Restricted to human observations from 2019 onwards — the same kind of record and the same period the probabilities on this page are built from, so collar-tracking studies, camera-trap arrays and museum specimens are excluded. Around Santa Rosa that removes 5,924 GPS fixes from a handful of tagged jaguars.
