Heterospecific eavesdrop** on an anti-parasitic referential alarm call
Referential alarm calls occur across taxa to warn of specific predator types. However,
referential calls may also denote other types of dangers. Yellow warblers (Setophaga …

Characterizing the timing of yolk testosterone metabolism and the effects of etiocholanolone on development in avian eggs
Maternal transfer of steroids to eggs can elicit permanent effects on offspring phenotype.
Although testosterone was thought to be a key mediator of maternal effects in birds, we now …

Eavesdrop** on referential yellow warbler alarm calls by Red-winged Blackbirds is mediated by brood parasitism risk
Referential alarm calls that denote specific types of dangers are common across diverse
vertebrate lineages. Different alarm calls can indicate a variety of threats, which often require …

Best of a bad job or masters of illusion: Do nest light conditions make the eggs of brood parasitic brown‐headed cowbirds (Molothrus ater) more similar to the eggs of …
Brown‐headed cowbirds (Molothrus ater) are generalist obligate brood parasites, laying in
the nest of nearly 300 avian species, and successfully parasitizing well over 100 host …

Inter-individual variation in anti-parasitic egg rejection behavior: a test of the maternal investment hypothesis
Hosts of avian brood parasites may reduce or forego the costs of caring for foreign young by
rejecting parasitic eggs from the nest. Yet, many host species accept parasitic eggs and …

Pairing status moderates both the production of and responses to anti‐parasitic referential alarm calls in male yellow warblers
Defending offspring incurs temporal and energetic costs and can be dangerous for the
parents. Accordingly, the intensity of this costly behavior should reflect the perceived risk to …

Developmental asynchrony and host species identity predict variability in nestling growth of an obligate brood parasite: a test of the “growth-tuning” hypothesis
Generalist obligate brood parasites are excellent models for studies of developmental
plasticity, as they experience a range of social and environmental variation when raised by …

In ovo metabolism of progesterone to 5β-pregnanedione in chicken eggs: Implications for how yolk progesterone influences embryonic development
Progesterone has received substantial attention for the essential role it plays in establishing
and maintaining pregnancy in placental vertebrates. Despite the prevalence of progesterone …

The brown-headed cowbird: A model species for testing novel research questions in animal ecology, evolution, and behavior
Although the brown-headed cowbird (Molothrus ater) is the most intensively studied brood
parasite in the world, much of the research on cowbirds has focused on the negative effects …

Responses of female yellow warblers to playbacks signaling brood parasitism or predation risk: A quasi-replication study
Many avian species are negatively impacted by obligate avian brood parasites, which lay
their eggs in the nests of host species. The yellow warbler (Setophaga petechia), which is …
