Grzywaczewski G. (2009) Home range size and habitat use of the Little Owl Athene noctua in East Poland. ARDEA 97 (4): 541-545
Home ranges of 11 Little Owls Athene noctua were studied using radio telemetry in agricultural landscapes of eastern Poland during the breeding seasons of 200003. Owls were tracked from the time of egg laying until the young dispersed (15 April 22 August). Areas of use were determined for three periods: egg laying and incubation period (15 April 17 May), nestling period (8 May 28 June), and fledgling period (29 June 22 August). During the egg laying and incubation period use areas were on average 18 ha (SD 20, 2.565.3, n = 9), during the nestling period 27.5 ha (SD 28.2, 1.995.0, n = 18), during the fledgling period 9.0 ha (SD 9.4, 1.834.1, n = 11). The majority of owl locations were recorded in fields (64%, mainly cereals). Fewer locations were in fields with row crops (12%, sugar beets, potatoes), on buildings (11%), gardens and orchards (9%), meadows and pastures (2%), roads (1%) trees and bushes (1%). During the breeding season, the growth of vegetation limited the access that owls had to the ground. Little Owls spent 8595% of their time at places where vegetation height did not exceed 20 cm.
