A test of the migration-modulation hypothesis in a non-passerine Neotropical migrant, the Blue-winged Teal Anas discors
Blue-winged Teal (Anas discors) initiate southward migration from their North American breeding grounds in late summer, making trans-Gulf flights to overwinter in South America. As such, this species displays a f...

Sex differences in the long-term repeatability of the acute stress response in long-lived, free-living Florida scrub-jays (Aphelocoma coerulescens)
There is increasing evidence that individual differences in the physiological stress response are persistent traits in many animals. To test the hypothesis that the stress-induced CORT (SI-CORT) response is re...

Hatching asynchrony that maintains egg viability also reduces brood reduction in a subtropical bird
In birds, hatching failure is pervasive and incurs an energetic and reproductive cost to breeding individuals. The egg viability hypothesis posits that exposure to warm temperatures prior to incubation decreas...

Here today, not gone tomorrow: long-term effects of corticosterone
There is a growing body of evidence from across animal taxa that exposure to elevated levels of glucocorticoids during development can have profound long-term effects upon physiological and behavioral phenotyp...

Older can be better: physiological costs of paternal investment in the Florida scrub-jay
In species that undergo actuarial senescence, the value of current reproduction is predicted to increase relative to the value of future reproduction with age, as the probability of survival to another reprodu...

RETRACTED ARTICLE: Latitude affects degree of advancement in laying by birds in response to food supplementation: a meta-analysis
Food supplementation experiments have provided considerable information about the importance of resource availability in timing reproduction. Supplemented birds usually advance breeding over non-supplemented c...

Cryptic plumage signaling in Aphelocoma Scrub-Jays
Recent studies of avian vision and plumage coloration have revealed a surprising degree of cryptic sexual dimorphism, with many examples of male–female differences in UV reflectance that are invisible to human...

Does Differential Access to Protein Influence Differences in Timing of Breeding of Florida Scrub-Jays (Aphelocoma coerulescens) in Suburban and Wildland Habitats?
—Timing of breeding in Florida Scrub-Jays (Aphelocoma coerulescens) varies both within and between years. Social status and breeding experience may explain much of the within-year variation, but the availability ...

Food supplementation and timing of reproduction: does the responsiveness to supplementary information vary with latitude?
Food supplementation usually advances the timing of laying. Here, we report a meta-analysis of 35 food supplementation studies demonstrating that species at high latitudes are less responsive to food supplemen...

Does optimal foraging theory explain why suburban Florida scrub-jays (Aphelocoma coerulescens) feed their young human-provided food?
Optimal foraging theory assumes that a forager can adequately assess the quality of its prey and predicts that parents feed their young low-quality foods only when suffering unpredicted reductions in their abi...

Nutritional quality of prebreeding diet influences breeding performance of the Florida scrub-jay
Food supplementation studies of breeding birds have traditionally concentrated on energetic constraints on breeding performance. It is only recently that the nutritional quality of the prebreeding diet has als...

Variation in the timing of breeding between suburban and wildland Florida Scrub-Jays: Do physiologic measures reflect different environments?
Evidence exists that access to anthropogenic food by birds in urban areas can result in earlier laying dates and larger clutch sizes, both of which have the potential to increase the relative fecundity of urba...

Delayed breeding in the cooperatively breeding Florida scrub-jay (Aphelocoma coerulescens): inhibition or the absence of stimulation?
To determine whether fundamental differences exist in the reproductive physiology of breeder and nonbreeder Florida scrub-jays (Aphelocoma coerulescens), we compared plasma levels of testosterone (T) and luteini...
