Abstract Incubation length and hatching asynchrony are integral elements of the evolved reproductive strategies of birds. We examined intra- and interpopulation variation in both traits for Eastern Kingbird (Tyrannus tyrannus) populations from New York (NY), Kansas (KS), and Oregon (OR) and found that both incubation length and hatching asynchrony were not repeatable among females, after controlling for a repeatable trait, clutch size. Instead, incubation length and clutch size were influenced by ambient temperature and precipitation. Incubation length exhibited the same median (15 days) and range (13–17 days) at all sites. Model selection results indicated that incubation periods for the smallest and largest clutches were longer in NY than KS when rain was frequent throughout incubation, in replacement nests, and likely when ambient temperatures were low during egg-laying. Full hatching usually required 2 days (but up to 3), with synchronous hatching associated with small clutch sizes, short incubation periods, frequent rain during the egg-laying period, and low ambient temperatures during the first half of incubation. Nestling starvation was uncommon (5–9% of nestlings monitored) and not associated with greater hatching asynchrony. These results indicate that while clutch size, a repeatable female trait, contributed to variation in incubation length and hatching asynchrony in Eastern Kingbirds, weather was a greater source of variation, especially for incubation length.

Preserve Blood

Abstract We stored blood samples of Eastern Phoebes (Sayornis phoebe) in a lysis buffer (“QLB”) that has been used successfully to preserve blood samples of many other species. We found that although samples from adults were not affected greatly, samples of nestling blood stored for more than a few days did not reliably produce the quantity and quality of DNA useful for multi-locus DNA fingerprinting. We also were unable to extract usable DNA from blood samples collected from Eastern Kingbird (Tyrannus tyrannus) nestlings, but obtained usable DNA from blood of Least Flycatcher (Empidonax minimus) nestlings stored for more than a year. We recommend that anyone planning DNA research with tyrant flycatchers should conduct their DNA extractions as soon as possible after collection. A pilot study to test methods of storage, preservation, and extraction may be necessary before beginning a large-scale project.

Abstract Genetic parentage in the socially monogamous and territorial Eastern Kingbird (Tyrannus tyrannus) was examined in a central New York population by multilocus DNA fingerprinting. Extra-pair young were identified in 60% (12 of 20) of nests. Of the 64 nestlings profiled, 42% were sired by extra-pair males, but no cases of conspecific brood parasitism were detected. These results are markedly different from a previous electrophoretic study of the same species in a Michigan population, which reported 39% of nestlings were unrelated to one (typically the mother, quasiparasitism) or both (conspecific brood parasitism) of the putative parents. In the New York population, extra-pair paternity was most common among females that returned to breed on a former territory. Among females that were new to a breeding territory, extra-pair paternity increased directly with breeding density. Although the power of the tests was low, neither breeding synchrony nor male experience with a breeding territory appeared to be associated with the occurrence of extra-pair young. Alta Frecuencia de Paternidad Extra-Pareja en Tyrannus tyrannus Resumen. Se examinó la paternidad genética de Tyrannus tyrannus, especie socialmente monógama y territorial, mediante la técnica de huellas dactilares genéticas de múltiples loci en una población de Nueva York central. En el 60% (12 de 20) de los nidos se identificaron juveniles con origen extra-pareja. De los 64 pichones investigados, el 42% fue engendrado por machos fuera de la pareja, aunque no se detectaron nidadas con parasitismo conespecífico. Estos resultados son considerablemente diferentes a los obtenidos en un estudio previo para la misma especie en una población de Michigan, el cual reportó que el 39% de los pichones no estaban relacionados con uno (tipicamente a la madre, cuasiparasitismo) o ambos (parasitismo de nido conespecífico) padres putativos. En la población de Nueva York, la paternidad extra-pareja fue más común entre hembras que retornaron a criar a territorios que habían ocupado previamente. Entre las hembras que ocuparon por primera vez un territorio de cría, la paternidad extra-pareja aumentó directamente con la densidad de individuos reproductivos. A pesar que el poder del análisis fue bajo, ni la sincronía reproductiva, ni la experiencia de los machos en sus territorios de cria, parecen estar asociados a la ocurrencia de juveniles extra-pareja.
