  • Dietary opportunism, resource partitioning, and consumption of coffee berry borers by five species of migratory wood warblers (Parulidae) wintering in Jamaican shade coffee plantations

    Dietary opportunism, resource partitioning, and consumption of coffee berry borers by five species of migratory wood warblers (Parulidae) wintering in Jamaican shade coffee plantations

    Nonmetric Multi-Dimensional Scaling with 95% confidence ellipses for species centroids (based on weighted averages), and hulls (convex polygons for all observations per species), based just on March 2000 data. NOPA, Northern Parula; AMRE, American Redstart; PRAW, Prairie Warbler; BTBW, Black-throated Blue Warbler; and BAWW, Black-and-white Warbler. See Fig.  legend for arthropod taxa codes.

  • Post-fledging survival of altricial birds: ecological determinants and adaptation

    Post‐fledging survival of altricial birds: ecological determinants and adaptation

    Frequency of reports of proximate causes of post-fledging mortality (left) and of modulating factors of post-fledging survival (right, including multiple results per paper). Predation, or predation or starvation, were mentioned as the major cause of mortality in 72% of the studies (N = 68 papers). Of the papers that provided evidence for factors modulating post-fledging survival rates, 35% mentioned fledgling mass and/or fledging date as main influences. Parental effects (post-fledging care, brood size, and age) were detected in 6% of studies. Habitat structure was also shown to significantly affect post-fledging survival (15%).

  • Breeding biology and egg temperatures of Black-faced Brush-finches (Atlapetes melanolaemus), Neotropical montane songbirds

    Breeding biology and egg temperatures of Black‐faced Brush‐finches (Atlapetes melanolaemus), Neotropical montane songbirds

    Nest, eggs, and nestlings of Black-faced Brush-finches in Manu National Park, Peru. (A) Nest and eggs in natural placement among thick grasses and ferns, showing the interior nest layer composed of grasses. (B) Nest after collection, showing the outer layer composed of Chusquea bamboo leaves. (C) Eggs. (D) Three-day-old nestling. (E) Twelve-day-old nestling. Photographs by T. R. Forrester.

  • Evidence for longitudinal migration by a “sedentary” Brazilian flycatcher, the Ash-throated Casiornis

    Evidence for longitudinal migration by a “sedentary” Brazilian flycatcher, the Ash‐throated Casiornis

    Variation in longitudinal position (y-axis) of Ash-throated Casiornis records during the annual cycle (x-axis) and mean annual precipitation rates (z-axis) at Petrolina. Triangles represent specimen records, circles are sight records on eBird, and squares are images on WikiAves. Green/dark gray denotes records from Amazonia, orange/mid gray from the Cerrado, black from the Atlantic Forest, and yellow/light gray from the Caatinga.
