From:The American Biology Teacher (Vol. 70, Issue 3) Peer-ReviewedThe Importance of Analogies to Science Analogies are an integral feature of scientific theories, like evolution. They are developed to support explanations, proposed on the basis of evidence collected from...

From:The Wilson Journal of Ornithology (Vol. 130, Issue 4) Peer-ReviewedAccumulation of human-made debris in seemingly pristine habitats is a problem occurring across a broad range of ecosystems. Such debris can be detrimental for wildlife, leading to choking, ingestion of toxic materials,...

From:BioScience (Vol. 59, Issue 2) Peer-Reviewed"It seems to be a little world within itself, the greater number of its inhabitants, both vegetable and animal, being found nowhere else," Charles Darwin wrote. His reconnaissance of the Galapagos Islands in 1835 was...

From:Ecology (Vol. 77, Issue 2) Peer-ReviewedThree species of Darwin's finches (Geospiza fortis, G. scandens, and G. fuliginosa) hybridize rarely on the small Galapagos island of Daphne Major. Following the exceptionally severe El Nino event of 1982-1983, hybrids...

From:The Wilson Journal of Ornithology (Vol. 129, Issue 2) Peer-ReviewedABSTRACT,--The Vegetarian Finch, Platyspiza crassirostris, is a relatively unstudied Darwin's finch that appears to be in decline in the Galapagos Islands. We monitored 11 nests of Vegetarian Finches during 2013 and...

From:Evolution (Vol. 47, Issue 5) Peer-ReviewedA study was conducted to investigate the mechanism of color expression in the house finch Carpodacus mexicanus and how this mechanism affects its sexual behavior. The display of colorful plumage in males and drab brown...

From:Wilson Bulletin (Vol. 107, Issue 3) Peer-ReviewedA study has been conducted to examine the response of female Red Crossbills to dietary carotenoid supplementation. Male and female Red Crossbills were captured and treated with diets enhanced with red carotenoid pigments...

From:Evolution (Vol. 49, Issue 2) Peer-ReviewedA study was conducted on the natural colonization of the island Daphne Major in the Galapagos archipelago by the large ground finch. Results revealed unusually high inbreeding levels, but low inbreeding depression...

From:Science (Vol. 305, Issue 5689) Peer-ReviewedDarwin's finches are a classic example of species diversification by natural selection. Their impressive variation in beak morphology is associated with the exploitation of a variety of ecological, niches, but its...

From:Nature (Vol. 464, Issue 7292) Peer-ReviewedBiol. Lett. doi:10.1098/rsbl.2010.0165 (2010) In Darwin's finches, males learn to sing from their fathers. Song types can persist from one generation to the next, but for how long? Eben Goodale and Jeffrey Podos...

From:Evolution (Vol. 48, Issue 2) Peer-ReviewedHybridization among three species of Darwin's finches was studied with respect to the morphological consequences of inter-breeding. An examination of hybrids and backcrosses of Geospiza fortis, Geospiza scandens and...

From:Wilson Bulletin (Vol. 112, Issue 1) Peer-ReviewedJ. Dylan Maddox [1,2] Eric K. Bollinger [1,3] ABSTRACT.--We observed male Dickcissels (Spiza americana) commonly feeding nestlings in Conservation Reserve Program (CRP) fields in 1997 in east-central Illinois....

From:Ecology (Vol. 77, Issue 2) Peer-ReviewedThis paper examines the role of pollen digestion in the early breeding of Darwin's finches. Pollen is a rich source of protein, but the extent to which birds digest pollen has been debated. On Isla Daphne Major,...

From:Evolution (Vol. 49, Issue 2) Peer-ReviewedPredicting the impact of natural selection on the microevolution of quantitative traits in wild animal populations require careful studies of the offspring of parents in a selected group. By applying this principle to...
-
From:Wilson Bulletin (Vol. 111, Issue 1) Peer-ReviewedIn a series of choice tests, we determined the relative preferences of House Finches (Carpodacus mexicanus) for equicaloric aqueous solutions of hexoses (1:1 mixture of fructose and glucose) and sucrose. At 2% (m/v),...
-
From:Wilson Bulletin (Vol. 112, Issue 3) Peer-ReviewedSandra J. Webster [1] Louis Lefebvre [1,2] ABSTRACT.--Generalist birds are thought to be less neophobic than specialists, but the dietary difference is often confounded by differences in experience and food...
-
From:Evolution (Vol. 50, Issue 6) Peer-ReviewedStudies of songs by two sympatric congeneric species of Darwin's finches on Daphne Major, Galapagos Island, showed that the bird sings one song that is retained throughout life by males. Although songs of the Geospiza...

From:PLoS ONE (Vol. 13, Issue 9) Peer-ReviewedComparing the functional performance of biological systems often requires comparing multiple mechanical properties. Such analyses, however, are commonly presented using orthogonal plots that compare N [less than or...

From:Wilson Bulletin (Vol. 108, Issue 1) Peer-ReviewedThe American Goldfinch has made use of purple loosestrife as a nest substrate in different habitats. The non-indigenous plant is found in parks and yards with ornamental vegetation and in moist fields and similar areas....
