“…In common with many other wild avian rehabilitation studies (Fix and Barrows 1990; Sweeney et al 1997;Deem et al 1998;Morishita et al 1998;Punch 2001;Wendell et al 2002;Komnenou et al 2005;Kelly and Bland 2006;Harris and Sleeman 2007), the majority of cockatoos in this study (at least 76.7%) presented with trauma. Human activities contributed to a significant number of trauma cases (28%) and were likely to have been responsible for many more due to unconfirmed vehicle strikes and shootings.…”

“…Our results may also provide more relevant information for other wild psittacine rehabilitation programs, as previously published retrospective studies on rehabilitated wild birds have involved nonpsittacine species (Fix and Barrows 1990;Sweeney et al 1997;Deem et al 1998;Morishita et al 1998;Punch 2001;Wendell et al 2002;Ress and Guyer 2004;Komnenou et al 2005;Kelly and Bland 2006;Harris and Sleeman 2007;Molony et al 2007;Rodrí-guez et al 2010). In addition, few studies published to date on other bird species examined variables associated with signalment and presenting condition relating to rehabilitation success (Ress and Guyer 2004;Molony et al 2007) as opposed to listing the causes and characteristics of morbidity and mortality (Fix and Barrows 1990;Sweeney et al 1997;Deem et al 1998;Morishita et al 1998;Punch 2001;Wendell et al 2002;Komnenou et al 2005;Harris and Sleeman 2007).…”

“…This is the first published retrospective analysis of factors influencing rehabilitation success of Australian psittacine birds. Most studies on avian rehabilitation involve raptor species in North America and Europe (Ress and Guyer 2004;Komnenou et al 2005;Harris and Sleeman 2007;Rodríguez et al 2010).…”

ABSTRACT:The veterinary records of three species of free-living, endangered black cockatoos (Calyptorhynchus spp.; n5565) admitted to the Perth Zoo Veterinary Hospital in Western Australia during a 10-yr period (2000-09) were analyzed to determine the effect of clinical presentation and treatment on survival to release. The most-common reason for admission was trauma (at least 76.7% of cases), and trauma was also the most-frequent finding on necropsy examination (80.1% of cases). Anemia and paralysis-paresis were significant factors determining the decreased likelihood of survival of cockatoos undergoing rehabilitation. Human activities, in particular vehicle strike, were significant causes of morbidity and mortality in free-living black cockatoo populations.

“…Wildlife rehabilitation outcomes have been focused in the proportion of releases taking into account the causes of admission (Richards et al, 2005) or the species (Harris and Sleeman, 2007), but rarely combining both variables (Ress and Guyer, 2004). Moreover, differences in the number of cases or in the methodological approaches make comparisons of the results difficult.…”

“…The rehabilitation of wild birds of prey and owls, nowadays extensively developed in many countries, has played a significant improvement in wildlife medicine and wildlife conservation of species, including positive input on the recovery of some endangered species (Negro et al, 2007), the identification and understanding of many menaces to the wild populations (Harris and Sleeman, 2007) and the improvement of animal welfare (Grogan and Kelly, 2013). The main goal of the rehabilitation of wild life species is to be able to release individuals to the wild after physical and behavioral recovery, taking into account, not only welfare concerns but also providing a critical evaluation of the chances of individual to survive in the wild after rehabilitation.…”

Outcome research of rehabilitation of wild birds of prey and owls are scarcely reported. The aim of this study is to investigate specie-specific outcomes of the rehabilitation practice in wild raptor attended in a wildlife center. A total of 6221 hospitalized wild raptors (3241 Strigiformes; 2980 Falconiformes) admitted at a Wildlife Rehabilitation Centre (WRC) of Catalonia from 1995 to 2007 were analysed. The outcomes indicators were based on ratios of Euthanasia (E r ), Mortality (M r ), Release (R r ) and Captivity (C r ). Stratified analyses by main causes of admission were performed for the different raptor species. Species from the Falconiformes order presented higher rates of euthanasia (33.9%) compared to the Strigiformes (18.6%). Species like B. buteo (45.7%) and M. migrans (47.6%) in the Falconiformes and B. bubo (33.6%) in the Strigiformes, presented the highest E r . Despite no differences between orders could be observed in the row mortality rates, data analysed by the causes of admission showed that the M r of owls was significant higher than the Falconiformes for the trauma (13.2%; χ 2 = 49.97; p<0.001), non trauma (12.7%; χ 2 = 17.41; p<0.001) and orphaned young categories (4.9%; χ 2 = 5.4; p = 0.02). The release rate was similar between orders. Based on species, G. fulvus (69.2%), C. aeruginosus (56.3%) and A. gentillis (43.1%) in the Falconiformes and O. scops (48.5%) in the Strigiformes showed the highest R r . In the orphaned young category owls had better R r than the diurnal raptors, being S. aluco the specie with the best rates of release (84%), whereas B. bubo had the worst values (50%). Specie-specific differences were found in the rehabilitation outcomes according to the different causes of admission. The stratified analysis of outcomes can be useful in order to to identify specie-specific risk factors.

Sources of lead exposure of many bird species are poorly understood. We analyzed blood lead concentrations from osprey (n = 244; Pandion haliaetus) and bald eagles (n = 68; Haliaeetus leucocephalus) and documented potential sources of lead they may encounter. Adult bald eagles had higher blood lead concentrations than did adult osprey. However, blood lead concentrations of nestlings were similar for both species. Although 62% of osprey had detectable lead concentrations (x¯ = 1.99 ± 4.02 μg/dL, mean ± standard deviation [SD]), there was no difference in the detection frequency or lead concentrations between osprey adults and nestlings. Likewise, we found no differences in the detection frequency or lead concentrations in osprey adults and nestlings from high‐ and low‐salinity areas. Of the bald eagle samples tested, 55% had detectable lead levels (x¯ = 6.23 ± 10.74 μg/dL). Adult bald eagles had more detectable and higher lead concentrations than did nestlings or pre‐adults. Among environmental samples, paint had the highest lead concentrations, followed by sediment, blue catfish (Ictalurus furcatus), and gizzard shad (Dorosoma cepedianum). There was no correlation between blood lead concentrations of osprey adults and their offspring. Our results indicate that, in the Chesapeake Bay region of Maryland and Virginia (USA), there are multiple sources by which piscivorous raptors may be exposed to lead.
