Niche position and niche breadth effects on population abundances: A case study of New World Warblers (Parulidae)
Published 2024-03-01“…In this study, we investigated the influence of niche position and breadth on the abundance of 47 species of birds belonging to the Parulidae family, commonly known as New World Warblers. We obtained data on abundance and presence records spanning the reproductive distribution of these species and employed the outlying mean index analysis to calculate niche position and niche breadth. …”

A new species of Isospora (Apicomplexa: Eimeriidae) from the yellow warbler, Setophaga petechia (L.) (Passeriformes: Parulidae: Parulinae), in Oklahoma, USA
Published 2022-01-01“…The oöcysts of I. fitzpatricki n. sp. can be differentiated from five other congeners reported from members of the New World warbler family Parulidae from either Mexico, Costa Rica, or Brazil, by being larger on average as well as by possessing a prominent rounded sub-Stieda body, sporozoite striations, and an posterior refractile body. …”

Migratory singers dynamically overlap the signal space of a breeding warbler community
Published 2024-02-01“…Here, we explore the impact of migratory species on a breeding community using the framework of acoustic signal space, a limited resource in which sounds of species within communities co‐exist. Migrating New World warblers (Parulidae, hereafter referred to as migrant species) often sing during refueling stops in areas and at times during which locally breeding warbler species (hereafter breeding species) are singing to establish territories and attract mates. …”

Site-infidelity by budworm-linked warblers at the edge of an area defoliated by spruce budworm
Published 2021-06-01“…We hypothesized that return rate of budworm-linked warblers will be high, as reported in other species of New World warblers, and we predicted that among habitat characteristics, return rate will increase with the density of SBW larvae. …”

Patterns of vagrancy and long-distance dispersal in migratory birds
Published 2021“…External factors that may drive vagrant occurrence were also examined. For vagrant New World warblers, the size of the overall breeding population and vagrant distance were found to best predict vagrancy. …”
