“…All According to our data, 57.57% of raptors admitted alive to the TWRC were successfully released, while 41.98% of admissions resulted in euthanasia or unassisted mortality. A comparative analysis between studies regarding final outcome of raptors in wildlife rehabilitation centers is difficult due to the heterogeneity of surveys (Duke et al, 1981;Fix & Barrows, 1990;Deem et al, 1998;Rodríguez et al, 2010;Thompson et al, 2013;Molina-López et al, 2013. The stratified analysis by causes of admission of the four final outcome rates (E r , M r , R r , and C r ), and the parameters time until death (T d ) and length of stay at the center (T r ), should be included in the outcome research of the rehabilitation process of raptors in order to allow comparative studies between wildlife rehabilitation centers around the world (Molina-López et al, 2013).…”
