Capsule Barn Owl pellets can be used to assess population changes in small mammals though with certain important reservations. Aims To conduct a large-scale, long-term analysis of pellets regurgitated by Barn Owls collected from a defined area of countryside within the UK south Midlands and compare results with those of other studies that have used pellet analysis to investigate the diet of Barn Owls. Methods Over 61 000 Barn Owl pellets collected over 20 years in the south Midlands of England were analyzed. Results We recorded a steady increase in the proportion of Field Voles in pellets over time at the expense of Wood Mice, and a positive relationship between various rainfall measures and the proportion of Field Voles in pellets. We suggest that the conclusions of previous studies of the diet of Barn Owls have often been predicated on inconsistent or untenable assumptions. Conclusion We challenge some of the premises on which Barn Owl pellet analyses have traditionally been based. We do not think that ...

The use of barn owl Tyto alba pellets to assess population change in small mammals

Small mammal studies require traps that efficiently capture the target species, are cheap, and preferably have no adverse effects on the animals. We compared the trapping efficiency of Ugglan multiple-capture live-traps with Longworth single-capture live-traps in field studies of house mice (Mus domesticus) in the Victorian Mallee of south-eastern Australia. More captures and recaptures were made with Longworth traps and fewer mice died while in these traps. There was no difference in mean body mass of captured mice between Ugglan and Longworth traps but relatively more males were trapped with Ugglan traps. The trapping mechanism that requires the mouse to activate a trap door, and open mesh wire along the sides of the Ugglan trap may be the main reasons for low trappability. In addition, the open sides could have contributed to the lower survival observed for mice in Ugglan traps. Although Ugglan traps have the potential for multiple captures, are cheaper, and their trapping mechanism is less prone to failure than Longworth traps, they were not as efficient in trapping house mice at low and medium densities.
