PIE LTER surveys of salt marsh breeding birds using point counts in Rowley and Newbury, Massachusetts
This data set contains the results of point count surveys of breeding birds in the salt marshes of the Plum Island Estuary. Surveys have been carried out each year in June beginning in 2004 and are ongoing. Currently six circles of 100 m radius are being surveyed. Three of the circles are in plots that had been regularly hayed and three in unhayed plots. Currently only one of the plots is regularly hayed. 85 species recorded as of 2020. Most frequently encountered are Agelaius phoeniceus, Ammospiza caudacuta, Tringa semipalmata.
Lake Superior NERR, Black Ash Habitat and Breeding Bird Survey, St. Louis River Estuary, WI, 2021
This dataset documented breeding bird communities within black ash forest stands along the shores of the St. Louis River Estuary in 2021. Breeding bird abundance was measured across multiple black ash stands that varied in canopy cover percent, understory density, and overall structural complexity. Data from this work supports the Lake Superior National Estuarine Research Reserve and collaborating partners in their ongoing ecological monitoring and habitat management in the St. Louis River Estuary. Data could be compiled with other regional breeding bird surveys or forestry data.

Supplementary data for "Influence of prey availability on habitat selection during the non-breeding period in a resident bird of prey"
<p><strong>Abstract</strong></p> <p>Background: For resident birds of prey in the temperate zone, the cold non-breeding period can have strong impacts on survival and reproduction with implications for population dynamics. Therefore, the non-breeding period should receive the same attention as other parts of the annual life cycle. Birds of prey in intensively managed agricultural areas are repeatedly confronted with unpredictable, rapid changes in their habitat due to agricultural practices such as mowing, harvesting, and ploughing. Such a dynamic landscape likely affects prey distribution and availability and may even result in changes in habitat selection of the predator throughout the annual cycle.</p> <p>Methods: In the present study, we 1) quantified barn owl prey availability in different habitats across the annual cycle, 2) quantified the size and location of barn owl breeding and non-breeding home ranges using GPS-data, 3) assessed habitat selection in relation to prey availability during the non-breeding period, and 4) discussed differences in habitat selection during the non-breeding period to habitat selection during the breeding period.</p> <p>Results: The patchier prey distribution during the non-breeding period compared to the breeding period led to habitat selection towards grassland during the non-breeding period. The size of barn owl home ranges during breeding and non-breeding were similar, but there was a small shift in home range location which was more pronounced in females than males. The changes in prey availability led to a mainly grassland-oriented habitat selection during the non-breeding period. Further, our results showed the importance of biodiversity promotion areas and undisturbed field margins within the intensively managed agricultural landscape. </p> <p>Conclusions: We showed that different prey availability in habitat categories can lead to changes in habitat preference between the breeding and the non-breeding period. Given these results we show how important it is to maintain and enhance structural diversity in intensive agricultural landscapes, to effectively protect birds of prey specialised on small mammals. Hereafter we provide the datasets and R script to reproduce the resource selection functions.</p>
Breeding Bird Community Surveys in the Huron Mountains, Marquette Co., Michigan (1997-1999).
Dr. Michael Kielb and collaborators conducted repeated surveys in June and July of 1997, 1998, and 1999, of breeding-bird communities along seven permanent transects in diverse habitats (old-growth forests, secondary forests, wetlands, riverine systems, etc.) within the boundaries of the Huron Mt. Club. Permanent 'listening-points' were established along each transect at intervals of ca. 200 m (7-20 points per transect), and numbers of singing birds tallied at each point. Data reported here are totals, by species, per transect. Detailed information on transect and point locations may be found in attached documents (reports to the Huron Mountain Wildlife Foundation) in .pdf format. Documents also include additional ad hoc observations. This study was repeated in 2020-2021, using the same transects and sampling points, by Ryan Buron and Harrison Jones, then graduate students at University of Florida; data from this follow-up study will be archived at EDI as a separate data-package.
Itasca Biological Station Bear Paw Point Breeding Bird Census, MN (1979-2025)
This dataset is part of an ongoing effort that began in 1979 at the University of Minnesota Itasca Biological Station to conduct an annual census of breeding bird territories on Bear Paw Point every spring. Students enrolled in Field Ornithology used an established 50x50 meter grid (11.5 hectares total plot size) and walked gridlines, identifying bird songs and estimating the number of singing males heard to determine the number of breeding territories for different species present on Bear Paw Point.
Itasca Biological Station Wilderness Loop Breeding Bird Survey, MN (1979 - 2025)
This dataset is part of an ongoing effort that began in 1979 at the University of Minnesota Itasca Biological Station to conduct a springtime annual survey of breeding birds around the Wilderness Loop drive in Itasca State Park. Following traditional USGS Breeding Bird Survey methods, Field Ornithology students conduct 3-minute point counts along an established route with 18 stops approximately 0.5 miles apart in distance. Students then recorded the species and number of birds seen and heard within a 0.25 radius.
Annual Point Count Breeding Bird Survey at Pepperwood Preserve in the California Coast Ranges 2007-2019
The Dwight Center for Conservation Science at Pepperwood is an ecological institute dedicated to educating, engaging, and inspiring our community through habitat preservation, science-based conservation, leading-edge research, and interdisciplinary educational programs. Our mission is to steward the life and landscapes of the 3,200-acre Pepperwood Preserve and to advance science-based conservation of ecosystems throughout our region and beyond. The Pepperwood Breeding Bird Survey was initiated in the spring of 2007 with the goal of establishing a set of baseline bird community data that would be built upon for years to come. Four transects (totaling 38 points) are surveyed annually using standardized five-minute point count protocols outlined by the Point Reyes Bird Observatory (now called Point Blue Conservation Science; Ballard et al. 2003) and the Handbook of Field Methods for Monitoring Landbirds (Ralph et al. 1993). Surveys are conducted by experienced volunteers during the breeding season starting in late April and ending in June, with each transect surveyed a total of three times. The Rogers Creek and Martin Creek transects were established in 2007. The Weimar Flat and Pepperwood Road transects were established in 2008 and 2012, respectively, to ensure comprehensive coverage across the various habitats that occur at the preserve including Douglas-fir forest, mixed hardwood forest, oak woodland/forest, chaparral, and open grasslands. This dataset includes data collected between 2007-2019.
CBS06 Line transects surveys of breeding birds throughout Konza Prairie
Like CPB01 and PBG051, this dataset includes records of bird species based on line transect sampling. These surveys re-initiate most of the original KNZ transects surveyed from 1981-2009 (initiated by Zimmerma), continue the two focal 300-m transects conducted from 2011-2016 by Sandercock on watersheds C3A, C3B, C3C, C1A, and 1D, (but not the peripheral segments which have been dropped), and adds two new 300-m transects to additional watersheds with the goals of (i) replicating all surveyed treatments at the watershed level, (ii) adequately sampling the grassland habitats present on Konza as of 2017, (iii) capturing transitions in bird community in response to woody encroachment and fire reversal treatments. The goals are to document and quantify long-term changes in the population sizes of breeding birds at Konza prairie by obtaining a standardized measure of annual breeding bird abundance at the site level and individual watershed or treatment level.
Male song structure predicts offspring recruitment to the breeding population in a migratory bird
<p>Bird song is a classic example of a sexually selected trait, but much of the work relating individual song components to fitness has not accounted for song typically being composed of multiple, often-correlated components, necessitating a multivariate approach. We explored the role of sexual selection in shaping complex male song of house wrens (<em>Troglodytes aedon</em>) by simultaneously relating its multiple components to fitness using multivariate selection analysis, which is widely used in insect and anuran studies but not in birds. The analysis revealed significant variation in the form and strength of selection acting on song across different selection episodes, from nest-site defense to recruitment of offspring to the breeding population. Males that sang more song typically employed in close communication sired more offspring that were subsequently recruited to the breeding population than those that sang far-communication song. However, this relationship was not consistent across earlier selection episodes, as evidenced by non-linear selection acting on these song components in other contexts. Collectively, our results present a complex picture of multivariate selection on male song structure that would not be evident using univariate approaches and suggest possible trade-offs within and among song components at different points of the breeding season. </p>
Stable isotope analysis reveals shifts in diet of a breeding montane bird
<p><span>Insectivorous breeding birds require access to high quality prey to produce a successful nest. A lack of suitable prey (e.g., low nutritional quality or low invertebrate availability) that fulfill energetic demands can negatively affect nestling growth and survival. In high elevation ecosystems (>900 m), cooler and wetter climates can have negative influences on invertebrate availability which in turn can affect bird diets. Yet we lack studies of how diet composition changes over elevation gradients. Here, we assessed the diet of Swainson's Thrush (<em>Catharus ustulaus</em>) within the White Mountains, New Hampshire using stable isotope analysis and DNA metabarcoding. We found that the proportion of detritivore arthropods in thrush diets increased with elevation, while the proportion of predatory arthropods and overall niche-width declined. Further, we show that high-elevation thrushes had diets that were different in composition, but similar in diversity to thrushes at low-elevation sites. Lepidoptera, araneae, and coleoptera were important diet items across all elevations, but increases in woodlice and ghost spiders contributed to familial-level differences in diet composition at high-elevation sites. This research suggests montane breeding birds may be consuming low quality prey (i.e., millipedes) at high elevation sites, due to either availability or preference. With considerations due to climate change, environmental contamination, and residual impacts on the diet and nutrient availability for breeding montane birds, understanding diet composition changes along environmental gradients can provide information on nutrient availability for species that breed in harsh climatic conditions. Future work on invertebrate availability and nutritional composition, daily energy expenditure, and dietary niche would help contribute to important context to conserving montane birds within these sensitive, high elevation systems. </span></p>
Relative breeding timing and reproductive success of a resident montane bird species
<p>The phenological match-mismatch hypothesis predicts that animals that better synchronize critical life history events with the peak availability of their primary food source should have higher fitness. If phenological match-mismatch determines breeding success, most individuals in a population may be expected to breed simultaneously within a given year because selection has favored mechanisms that allow for the tracking of optimal food abundance. Therefore, individuals that breed too early or too late relative to the bulk of the population ("peak" of breeding) should experience decreased fitness. Using 11 years of data, we investigated the effect of relative breeding timing on breeding success in resident mountain chickadees (Poecile gambeli) across two elevations in the Sierra Nevada mountains, USA. Chickadees that bred during the peak of nesting did not have the highest breeding success; instead, birds that bred earliest performed best at high elevation, while at low elevation early and peak nests performed similarly. Breeding success decreased linearly with relative timing at both high and low elevations, and the relationship between breeding success and timing differed among years. Our results suggest that phenological match-mismatch may not be the main driver of within-year variation in breeding success in animals residing in montane environments.</p>
Structural equation modeling reveals determinants of fitness in a cooperatively breeding bird
<p>Even in well-studied organisms, it is often challenging to uncover the social and environmental determinants of fitness. Typically, fitness is determined by a variety of factors that act in concert, thus forming complex networks of causal relationships. Moreover, even strong correlations between social and environmental conditions and fitness components may not be indicative of direct causal links, as the measured variables may be driven by unmeasured (or unmeasurable) causal factors. Standard statistical approaches, like multiple regression analyses, are not suited for disentangling such complex causal relationships. Here, we apply structural equation modeling (SEM), a technique that is specifically designed to reveal causal relationships between variables, and which also allows to include hypothetical causal factors. Therefore, SEM seems ideally suited for comparing alternative hypotheses on how fitness differences arise from differences in social and environmental factors. We apply SEM to a rich data set collected in a long-term study on the Seychelles warbler (Acrocephalus seychellensis), a bird species with facultatively cooperative breeding and a high rate of extra-group paternity. Our analysis reveals that the presence of helpers has a positive effect on the reproductive output of both female and male breeders. In contrast, per capita food availability does not affect reproductive output. Our analysis does not confirm earlier suggestions on other species that the presence of helpers has a negative effect on the reproductive output of male breeders. As such, both female and male breeders should tolerate helpers in their territories, irrespective of food availability.</p>
