“…Our study and that of are the only ones that have calculated recapture probabilities of nonbled and bled birds, and neither study found a difference. Recapture-resighting probability of male kingbirds was uniformly high (p ≥ 0.96) regardless of blood-sampling state, which is consistent with previous studies that have shown that male kingbirds are extremely site-faithful (Murphy 1996b, Redmond et al 2009). Females disperse more than males (Murphy 1996b), which is the most likely explanation for why the overall recapture probability (independent of state) was lower in females.…”

This dissertation presents the results of a study that I undertook to better understand the breeding biology of Eastern Kingbirds (hereafter, kingbirds) Kingbirds exhibit relatively high breeding site fidelity, often returning to the same tree to nest in subsequent years. Both members of a pair provide parental care, but there are often specific duties performed by both male and female kingbirds. For example, males typically perform much of the vigilant nest defense that this species is well known for and contribute, to an extent, to the feeding of nestlings. Females, on the other hand, are entirely responsible for incubating and brooding.Beginning in 2002, most adults within the population of kingbirds at Malheur had been banded with a unique combination of three colored plastic leg bands and an aluminum USFWS band. Also, as many nests were located in each year as possible, and any young that survived to fledging age were banded with a unique combination of leg bands. Considerable effort was then spent each year to locate as many banded individuals as possible, which allowed me to document adult and juvenile survival.Annual survival rates of adult male and female kingbirds in the population at Malheur did not differ and were relatively high at approximately 0.65. Juvenile survival rate was approximately 0.29, indicating that slightly less than one-third of nestlings survive the interval between fledging and their first potential breeding season. Resighting probability ii was high for both sexes, although higher for adult males (0.94) than for adult female (0.84). The latter finding is consistent with the higher site fidelity of males than of females. Resighting probabilities for juveniles were much lower at 0.68 and 0.40 for males and females, respectively. Again, this was expected because natal site fidelity is typically much lower than breeding site fidelity. Compared to most other reports, resighting probability and return rates of juvenile kingbirds was high, presumably because the riparian habitats where kingbirds breed at Malheur function as an ecological island surrounded by, for kingbirds, unsuitable high desert habitat. Thus, unless they disperse very long distances, the only option for juvenile kingbirds is to begin nesting on the refuge.The collection of blood samples from birds has become an increasingly common practice in ornithology. The data that can be gained from these samples allow a number of interesting questions to be asked such as understanding the genetic mating system of a species, patterns of hormone secretion, and discerning migratory pathways via stable isotope analysis. The volume of blood collected is usually small and was assumed to cause no long-term negative effects on sampled individuals. However, few studies have rigorously examined the effect of blood sampling on survival. I used a multistate markrecapture analysis to assess the effect blood sampling on annual survival of kingbirds by combining the annual survival data described above with whether or not individuals ...

“…Strong philopatry predominantly among adult individuals was evident; they did not leave a colony, even if nesting conditions there were unfavourable due to high breeding pair density. The study colonies Site fidelity of this species males was not reduced significantly by poor nest success in a previous year (Murphy 1996). In the case of other animal species however, a lack of reproductive success may increase the dispersion of individuals within a population (Haas 1998, Grosbois et al 2003, Winkler et al 2004, Fowler 2005.…”

“…Large tyrannids such as kingbirds (Tyrannus spp.) are ideal subjects for the application of geolocators because (1) their body mass (>30 g) allows them to carry geolocators relatively easily; (2) they have relatively high annual survival and site fidelity (Murphy 1996), which improves geolocator recovery; and (3) they use open habitats, preventing shading of the geolocator. Here, we use geolocators to describe variation in the timing of migration, the distance and speed of migration, and the location and number of sequential wintering areas occupied by individual Eastern Kingbirds (T. tyrannus), Western Kingbirds (T. verticalis), and Scissor-tailed Flycatchers (T. forficatus), three species of tyrannids that have overlapping breeding ranges across the southern Great Plains of North America.…”
