In Hungary the Ferruginous Duck breeds mainly in fishponds with dense vegetation, reservoirs, oxbow lake, marshes. Most important populations live in Somogy, Hortobágy, Biharugra and Southern Great Plain. The former population decline has recently stopped, and an increase can be observed at certain places. Migrant, occasionally overwinters. The first birds arrive after thaw, and soon concentrate near the breeding sites. The autumn gathering starts in the second half of August, and the last birds leave the country by mid-October.
