Seasonal trend patterns observed in the admission and release of Birds of prey in a wildlife rescue centre in Sussex: a six-year study. By Carmella Amy Tebbutt

Data set includes: Falconiformes (Falcon Family) Peregrine Falcon - Falco peregrinusHobby - Falco subbuteo Strigiformes (Owls)Tawny Owl - Strix alucoLittle owl - Athene noctuaLong Eared owl - Asio OtusBarn owl - Tyto alba Accipitriformes (Hawks, Eagles and Kites)Sparrow hawk - Accipiter nisusKestrel - Falco tinnunculusBuzzard - Buteo buteo

Primary hypotheses:What are the main causes of birds of prey entering rescue centres?Secondary hypothesis: Does the abundance of the species have an effect upon the number of admitted causalities? Is there any correlation between admitted of bird of prey and season? What is the average rehabilitation time?Is there any correlation between season and rehabilitation time?Does the hunting behaviour of the species have an effect upon the numbers admitted to WRAS (wildlife rescue and ambulance service)Are there particular location in East Sussex associated with high numbers of casualties?Counts need to be taken with factors such as migration taken into account.AimsCritical review of birds of prey in rescue centres and the environmental factors that contribute to them being there.Scientific analysis of why birds of prey end up in rescue centres, with factors such as season, predatory behaviour, reason for admittance, likelihood of survival and rehabilitation time taken into account.

Motivations for choosing this study Work experience at WRAS, has allowed me to have a good understanding of current protocol at wildlife rescue centres and ensured that I have knowledge of birds of prey on a case by case basis. This study could allow rescue centres to have a better understanding of when cases are more likely to occur, and if so, what treatments are more likely to be required according to seasonal variance. The study will also look at hotspot location’s for casualties. The main motivation is to allow wildlife rescue centers to be more prepared for wildlife casualty cases and hopefully enhance the chances of survival and rehabilitation.

Literature supporting the research question. Description of the varying species and current UK conservation status:RSPB, has a vast range of information regarding all species present within my data. Description of the work WRAS does as an organisation for birds of prey:WRAS website gives details regarding how long they have been working as a organisation, and their telephone number. In addition an interview or questionnaire could be conducted to allow for a better understanding of protocol. Description of the level of protection birds of prey receive from the Wildlife and Countryside Act (1981), and how does this fit in with wildlife rescue centres:Legislation.GOV.uk has lots of information regarding legislation, including the Wildlife and Countryside Act 1981. Methodology, Why a six year study?Current studies on the “admissions, diagnosis, and outcomes for Eurasian Sparrowhawks brought to a wildlife rehabilitation centre in England” (Kelly & Bland, 2006). Have only been a five year study, however the data set available is of a six year period and will therefore hopefully give a better understanding of fluctuations in numbers of cases due to having a longer time span and having a larger data base. What might happen in the discussion? Some references that may be useful. Factors affecting release rates from RSPCA wildlife hospitals - a re-analysis (P. J. Baker and S. Harris . 2004).Rehabilitated and wild Barn Owls (Tyto alba): dispersal, life expectancy and mortality in Spain (I. Fajardo, G. Babiloni, and Y. Miranda . 2000). An investigation of the effectiveness of rehabilitation of birds as shown by ringing recoveries (A. C. Joys, J. A. Clark, N. A. Clark, and R. A. Robinson . 2003)

Results at a glance. Pie chart determining numbers of casualties per season. Spring – 24.9%Summer – 33.6%Autumn – 25.4%Winter – 16.1%Pie chart determining numbers of causalities according to classification (order) Strigiformes (owl family) – 50.5%Flanconidae (Falcon family) – 20.2%Acciptiformes (All other diurnal Birds of prey) – 29.2%Tawny owl and Sparrow hawk found to have the highest casualty rate.
