State of the UK Barn Owl Population 2013. This report, the first of it's kind, presents results from the checking of 6,344 potential Barn Owl nest sites by 26 independent individuals, groups, and dedicated Barn Owl projects. Although various factors behind population change are discussed, this report is only intended to answer simple questions such as 'how did Barn Owls do last year' or 'how do my results compare to others'. Overall, 2013 was the worst year ever recorded.

 

Rehabilitation Report - bird casualties received by the Barn Owl Trust in the period 1990-2005. This document presents figures on the number of bird casualties received by the Barn Owl Trust and what happened to them up to the point of release. Background information and a brief outline of the rehabilitation process are also included so as to provide the reader with an understanding of the Trust's involvement in this type of work.

 

Barn Owls and Rural Planning Applications - a Guide was published by BOT in Spring 2009 with support from Natural England. It provides the most thorough and up-to-date guidance available on all aspects of rural developments where Barn Owls are or might be an issue.

 

Barn Owls and Major Roads. Published by the Barn Owl Trust in 2003, this report describes the results of a 15-year research project highlighting the effects that major roads have had on Britain's Barn Owl population. Almost the entire British Barn Owl population is to some extent suppressed by the presence of major roads. Major road deaths have more impact on Barn Owls than any other animal due to their rarity and the frequency with which they are killed.

 

2004 Barn Owl Survey of Cornwall. A repeated census of the county Barn Owl roost and nest sites ten years on from the first in 1994.

 

2003 Barn Owl Survey of Devon. A repeated census of the county Barn Owl roost and nest sites ten years on from the first in 1993. The survey methods used rely on data already held by the Trust and so any developments in BOT's activities that may skew results between the two surveys are discussed.

 

Barn Owl Re-introduction Report 2001. This report briefly reviews the history of release of captive-bred Barn Owls in Britain and summarises the contents of other reports containing release data. The main body of the report reviews Barn Owl Trust (BOT) releases (between 1992 and 1996) and examines the subsequent nestling success and long-term survival of released birds.

 

Barn Conversion Research project. This report contains the results of the Trust's research into the effects of barn conversions carried out between 1990 and 1995, the Trust's first scientific paper: Ramsden, D.J. (1998) Effect of barn conversions on local populations of Barn Owls Tyto alba. Bird Study, 45, 68-76

1994 Barn Owl Survey of Cornwall. This was carried out in partnership with the Cornwall Birdwatching and Preservation Society (CBWPS). The survey was not designed to produce an accurate county population estimate, but to re-check all known roost and nest sites.

 

1993 Barn Owl Survey of Devon. This was carried out in partnership with the Devon Birdwatching and Preservation Society. All known roost and nest sites were re-checked in Devon to complete a population census of the county.

Barn Owl Re-introduction Report 1986-1989. This was the first ever report produced by the Barn Owl Trust. The discussion is based on 140 BTO-ringed Barn Owls from 24 release sites operated by the Trust. Ring recoveries are compared with those obtained from 71 wild pulli ringed in the same county and time period. Two release methods are compared and the importance of gradual release is discussed.
