A Brown-Capped Black-Capped Chickadee (Poecile Atricapillus) In Sarpy County, Nebraska, W. Ross Silcock, Phil Swanson

Nebraska Bird Review

Beginning 31 May 2021, Phil Swanson captured a series of videos and photos of an apparent family group of Black-capped Chickadees (BCCH). Five birds were seen together through 2 June, 2-4 through 6 June, and 2-3 through 9 June, during which all sightings included begging. Thereafter 1-2 birds per day were seen but without interactions between them. One of the family group had a brown cap (Figures 1, 2), and was presumably a juvenile based on its propensity for begging for food and partial replacement of its greater coverts (Pyle 1997). This condition has been described as “rare” (Sibley 2011), …

Summer Field Report, June-July 2021, W. Ross Silcock

Nebraska Bird Review

Last summer my opening sentences were: “Overall, this was a fairly routine summer although birders in Nebraska know that ‘routine’ still holds promise of a few happenings out of the ordinary. The summer season primarily examines new breeding records, range expansions, and changes in numbers, up or down.” This summer was also rather routine but had its share of startling events. Foremost among these were only the second colony breeding of American White Pelicans, involving 1200 on nests; two, possibly the same, male Evening Grosbeaks in the southeast; record late by about a month Townsend’s Solitaire; two Lincoln’s Sparrows together …

Diminishing Returns: Results Of Black Rail Surveys In Nebraska, Joel G. Jorgensen, Lauren Greenwalt, Nancy E. Drilling, Caleb Strand, Stephen J. Brenner

Nebraska Bird Review

The uncertain status of the Black Rail in Nebraska is problematic. Different authors have interpreted existing reports differently resulting in varying conclusions about the species’ status. The exercise of deciphering the limited details of existing reports and litigating their credibility is of little value. The Black Rail is now a threatened species and there is almost no published information on whether it occurs regularly in Nebraska. Furthermore, the species has not been searched for in any consistent form or systematic manner. Without information and understanding about the species’ occurrence, taking actions to benefit and protect this species will undoubtedly be …

Vertebrate Scavenger Diversity And Ecosystem Services Along An Elevational Gradient In Central Nepal, Aishwarya Bhattacharjee

Dissertations, Theses, and Capstone Projects

A growing number of studies recognize the ecological significance of vertebrate scavengers, and several species belonging to this diverse, functional guild are of high conservation importance around the globe. Studies on taxonomic and functional components of biodiversity often use elevation gradients to comprehensively examine patterns and drivers across multiple spatial scales. Yet, there are relatively few elevational studies on large vertebrates or multi-taxa guilds, and the related variation of their ecosystem services. In particular, scavenger research has largely focused on local-scale studies or regional/global comparisons of local-scale investigations. Moreover, these studies primarily consider taxonomic community characteristics and the patterns of …

Black-Throated Gray Warbler In Knox County, Nebraska, Mark A. Brogie

Nebraska Bird Review

The Nebraska Ornithologists’ Union Records Committee (NOURC) considers Black-throated Gray Warbler (Setophaga nigrescens) to be Accidental in Nebraska (NOURC 2017). Silcock and Jorgensen (2020) list a total of seven accepted records with only two occurring in fall: an adult male at the Hyannis Cemetery, Grant Co., 01 Sep 2002 (Brogie 2003) and a female at Oliver Reservoir, Kimball Co., 07 Sep 2001 (Silcock 2001). The following documents the third Nebraska fall record for Black-throated Gray Warbler, the third record east of the Nebraska Panhandle, the first for northeast Nebraska, and the only NOURC accepted record (#2338) in the last decade.

Plumage Characteristics Of The Long-Eared Owl (Asio Otus) In The Visible And Ultraviolet Spectra Of Light, Emily Griffith

All NMU Master's Theses

The study of plumage is a foundational aspect of ornithology, and the features of even a single feather can provide valuable information on an individual’s health, sex, or age. Recent discoveries on the abilities of birds to see in the ultraviolet (UV) spectrum has led to study of the UV-reactive characteristics of bird plumage and the biological significance of such plumage. Long-eared owls (Asio otus) possess a demonstrative capability to see UV light, and their plumage contains deposits of UV-sensitive pigments that fluoresce bright red when exposed to UV light. Little is understood about the origin and function of these …

Purpose of our Study:

To investigate how UAS technologies could be safely and effectively applied to identify hazardous wildlife species to aviation operations as well as potential wildlife hazard attractants within the airport jurisdiction.

Effects Of Early Corticosterone Treatment On Vocal Babbling In Wild Green-Rumped Parrotlets (Forpus Passerinus), Celia Rose Mclean

Theses and Dissertations

The stress axis of the endocrine system allows for animals to respond to environmental stressors in contextually appropriate ways. Elevated levels of the stress hormone corticosterone (CORT) in male songbirds can result in compromised song learning ability. Parrots form a sister group to songbirds, but it is unknown whether CORT affects vocal development in parrots. The goal of this study was to assess the effects of CORT supplements in green-rumped parrotlets (Forpus passerinus), a free-ranging parrot species in Venezuela. Bouts of vocal babbling were extracted from nest box videos and analyzed. CORT supplementation resulted in differences in babbling …

Habitat Use And Morphology Of Birds In "Intact" Amazonia Under Changing Climate, Vitek Jirinec

LSU Doctoral Dissertations

Neotropical forests contain the core of global avian diversity. Of these, the Amazon rainforest is the largest, but ~20% has already been lost to deforestation, inspiring research into the effects of clearing and fragmentation on forest birds. These studies have consistently shown that insectivorous birds that forage on or near the ground are the most sensitive species to forest disturbance. As a preamble to our study, we synthesized bird capture data collected over 40 years within continuous forest far from human disturbance. Remarkably, we found that terrestrial and near-ground insectivores have shown substantial abundance declines even within primary forest. The …

Spring Field Report, March - May 2021, W. Ross Silcock

Nebraska Bird Review

A total of 163 observers contributed to this report. This spring several observers were quite active statewide, resulting in interesting discoveries among waterfowl hybrids, subspecies distributions, breeding and spatial range expansions, and more than usual early and late dates and high counts, not to mention a couple of extreme rarities. Speaking of BONO, readers will note a new section under “Species Accounts” that deals with hybrids reported in Nebraska. A surprising 47 are listed, 26 of these waterfowl. If you like waterfowl hybrids, read on! This report deals with 14 such hybrids, four newly documented for the state. Several non-waterfowl …

Paul Austin Johnsgard: Memories Of An Exceptional Naturalist, Allison E. Johnson, Charles R. Brown

Paul has told you in his own words in the previous pages where he was from, where he was educated, about the immense number of scholarly articles and books he published, and about his beautiful art that brought the wild to all of us (https://digitalcommons.unl.edu/zeabook/30/), but we wanted to share the person we knew Paul to be, and to relive some of our memories of him. While Paul’s body of work will continue to impact the ornithological and …

Incorrectly Aged, Identified And Classified: Revisiting Nebraska’S 1968 ‘Barnacle Goose’ Record, Joel G. Jorgensen, Stephen J. Brenner, W. Ross Silcock

Nebraska Bird Review

On 2 November 1968 in northeastern Otoe County, Nebraska, Milton Muncie harvested a bird (herein referred to as the 1968 specimen), subsequently identified as an immature Barnacle Goose (Branta leucopsis), from a flock of about 40 Cackling Geese (Branta hutchinsii; Cortelyou 1969). The occurrence was reported not only as the first record of a Barnacle Goose for Nebraska, but also the first record for the North American Interior and West (Cortelyou 1969). Cortelyou’s (1969) brief article also included a photograph of the mounted specimen. At the time and when subsequently reviewed by various authors, the identity of the 1968 specimen …
