We document molt extent; age-specific molt patterns, plumages, and percent of the bill with corrugations; the presence or absence of delayed plumage maturation and bill color changes in males of some species; and molt timing in the 19 resident hummingbird species of Belize. Molt strategies and rates of bill smoothing were similar to North American species, with all species showing limited to partial preformative molts, replacing only body feathers and some wing coverts and retaining all remiges and rectrices. Extent of bill corrugations reduced to ≤10% of bill length in all species by the time definitive cycle basic plumage is achieved. Males in sexually dichromatic species showed delayed maturation in plumage characteristics and/or bill coloration, and in two dichromatic species some older females showed male-like plumage. Nine species representing multiple clades showed advanced timing to the second prebasic molt, indicating that this trait may be a proximal response to individuals not breeding during the first molt cycle. Species with advanced second prebasic molts replaced fewer wing coverts during the preformative molt than species with later molt timing.","PeriodicalId":15785,"journal":{"name":"Journal of Field Ornithology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71043165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lined Seedeaters Sporophila lineola , an intra-tropical migratory songbird, exhibit extensive phenotypic variation, with characteristic black-and-white male and brownish female plumages. In this study, we investigated whether variation in male plumage represents delayed plumage maturation, as reported for many other Sporophila seedeaters. We used data on molt and plumage from a seven-year-long study of color-banded Lined Seedeaters in southeastern Brazil. We also gathered molt and plumage data from museum collections and citizen-science platforms to identify which molts occur outside the breeding grounds. Our findings show that Lined Seedeaters follow a complex basic strategy, but the possibility that some individuals exhibit a complex alternate strategy, which is a common strategy among congeners, cannot be ruled out. Preformative molt and fresh formative plumage were recorded within the breeding grounds in the last months of the breeding season. Prebasic molt also start on the breeding grounds and probably continue during migration to the wintering grounds. Observed phenotypic variation in plumage of Lined Seedeater males is a product of delayed plumage maturation. Breeding males in female-like plumage are formative individuals in their first breeding season. All monitored males acquired black-and-white definitive plumage after their first breeding season, during the second pre-basic molt, but we found limited evidence that some individuals may retain the brownish plumage for more than one cycle. Descriptions presented here advance our understanding of Sporophila molt","PeriodicalId":15785,"journal":{"name":"Journal of Field Ornithology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71043570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conservation of a migratory species requires knowledge not only of its breeding range, but also of its migratory path and non-breeding range. Except for timing, other aspects of the migration of the Ruby-crowned Kinglet ( Corthylio calendula ) remain largely unstudied, with no published data on migration routes. Breeding populations of this species in the Sierra Nevada and Cascades mountain ranges, as well as those in eastern Canada and the northeastern U.S., have experienced significant declines, whereas Rocky Mountain breeders have increased. Understanding the winter range and migratory pathways used by different breeding populations may be key to explaining these contrasting population trends. Song dialects of the Ruby-crowned Kinglet differ regionally among various breeding populations, and these dialect regions were previously mapped. Because this kinglet sings during spring migration and winter, we obtained archived, non-breeding-season recordings of song and assigned each to one of those regional song dialects. This allowed us to assess the likely winter ranges and migration pathways of different breeding populations. This approach offers some advantages over typical methods of tracking movements. Birds do not need to be captured; one can easily obtain data over large ranges and from many individuals; and it can be applied to species, such as this kinglet, that are too small to permit use of most tracking devices. We were able to assess likely winter range and spring migration routes for populations that breed in the eastern U.S. and Canada, the interior of Alaska, and for the subspecies C c. grinnelli that breeds along the Gulf of Alaska and western British Columbia","PeriodicalId":15785,"journal":{"name":"Journal of Field Ornithology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71043637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Climate change has resulted in changes to ecosystems and weather because of earlier onset of spring weather, later onset of fall weather, and more extreme weather patterns. Migratory birds may experience challenges adjusting to these new conditions. We utilized community science data from eBird that spanned 2009–2018 to test for changes in distribution and migration of two North American swift species. We asked if Vaux’s Swifts ( Chaetura vauxi ) and Chimney Swifts ( Chaetura pelagica ) changed their breeding distribution, migration routes, timing of migration, or speed of spring and fall migration over time. Our results show that Vaux’s Swifts shifted their breeding centroid south-east and Chimney Swifts shifted their breeding centroid west. There was also a shift in Vaux’s Swifts migration route to the east, almost proportionate in magnitude to its eastern shift in breeding range. Vaux’s Swifts displayed an advance in their start of spring migration, and Chimney Swifts exhibited a delay in their start of fall migration. These responses may be due to earlier onset of spring and a possible delay of colder temperatures associated with the onset of fall conditions. Our results indicated that both species are breeding further away from the coastline and more toward central","PeriodicalId":15785,"journal":{"name":"Journal of Field Ornithology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71043936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we examined breeding season third-order roost site selection on B. Bryan Farms, Mississippi, from 2021 to 2022. We observed a quadratic relationship with average vegetation height, where roost site selection increased with increasing vegetation height to a point and then slightly decreased (β1 = 0.14084, 95% CI = 0.05, 0.24; β12 = -0.01005, 95% CI = -0.06, 0.04). However, uncertainty in the quadratic term was notable. Similarly, we observed a quadratic relationship with litter (β1 = 0.25479, 95% CI = 0.12, 0.39; β12 = -0.09606, 95% CI = -0.16, -0.04). We also found selection decreased linearly with increasing bare ground (β1 =-0.20938, 95% CI = -0.31, -0.11). Individual birds may require taller vegetation, greater visual obstruction, greater litter coverage, and lesser bare ground coverage for better concealment from nocturnal predators when they are roosting individually during the breeding season or are constrained by limited mobility (i.e., brooding). Understanding the vegetative composition, structure, and location of roost sites during the breeding season may provide land managers with a better understanding of the vegetative characteristics necessary during all phases of bobwhite life history. Our results provide the first information on bobwhite breeding season roost site selection, which will help to develop a more complete understanding of bobwhite habitat requirements and increase the effectiveness of habitat management and conservation efforts for this species of conservation concern.","PeriodicalId":15785,"journal":{"name":"Journal of Field Ornithology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135009871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Canada Warblers ( Cardellina canadensis ) are small Neotropical migrants whose populations are declining across most of their range. Understanding factors limiting Canada Warbler populations requires knowledge of population ecology across the full annual cycle, including migratory pathways and over-winter locations. Light-level geolocator tags have offered unprecedented insight into migratory ecology for many species, but previous studies suggest that geolocators may influence apparent return rates. We sought to determine if geolocators influence apparent return rates of adult male Canada Warblers breeding in West Virginia, USA. In 2020, we deployed geolocators on 32 birds and color banded an additional 78 birds without geolocators. The following year, 13 of 32 (40.6%) geolocator birds and 37 of 78 (47.4%) color-banded birds were detected with no significant difference in apparent return rates between groups ( χ ² = 0.19, p = 0.66). Although further evaluation of additional groups will be valuable, the lack of significant effect on adult male Canada Warblers suggests that the slightly lower return rate does not preclude the use of geolocators as a tool to assess the migration ecology of this small songbird of conservation concern","PeriodicalId":15785,"journal":{"name":"Journal of Field Ornithology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71043276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
