    21 Sep 2018 Lists of Victims and Hosts of the Parasitic

    version: 21 Sep 2018 Lists of victims and hosts of the parasitic cowbirds (Molothrus). Peter E. Lowther, Field Museum Brood parasitism is an awkward term to describe an interaction between two species in which, as in predator-prey relationships, one species gains at the expense of the other. Brood parasites "prey" upon parental care. Victimized species usually have reduced breeding success, partly because of the additional cost of caring for alien eggs and young, and partly because of the behavior of brood parasites (both adults and young) which may directly and adversely affect the survival of the victim's own eggs or young. About 1% of all bird species, among 7 families, are brood parasites. The 5 species of brood parasitic “cowbirds” are currently all treated as members of the genus Molothrus. Host selection is an active process. Not all species co-occurring with brood parasites are equally likely to be selected nor are they of equal quality as hosts. Rather, to varying degrees, brood parasites are specialized for certain categories of hosts. Brood parasites may rely on a single host species to rear their young or may distribute their eggs among many species, seemingly without regard to any characteristics of potential hosts. Lists of species are not the best means to describe interactions between a brood parasitic species and its hosts. Such lists do not necessarily reflect the taxonomy used by the brood parasites themselves nor do they accurately reflect the complex interactions within bird communities (see Ortega 1998: 183-184). Host lists do, however, offer some insight into the process of host selection and do emphasize the wide variety of features than can impact on host selection.

Several behavioral aspects of the Red-crested Finch Coryphospingus cucullatus (Statius Müller, 1776) are poorly studied. Here we provide reproductive information on 16 active nests. This information may be valuable to elucidate the phylogenetic relationships of this bird, and to design plans to manage it. Nesting activities occurred from October to February. Clutches consisted of two to three eggs (2.06 ± 0.25), which were laid on consecutive days. Incubation usually started the morning the females laid their last egg and lasted 11.27 ± 0.47 days. Hatching was synchronous, or happened at a one-day interval. The nestling stage lasted 12 ± 0.89 days. Only females incubated the eggs and they fed the young more often than the males did. Overall nesting success, from incubation to fledging, was 28.2%. Nest architecture and egg color proved to be diagnostic characteristics of Coryphospingus, supporting its maintenance as a distinct genus within the recently proposed sub-family Tachyphoninae. Red-crested Finches showed a preference for certain nesting sites, i.e., forest borders or a Cerrado in late regeneration stage.

    Birds vs. Butterflies: Exhibiting Tropical Passerines and Lepidoptera in the Osher Rainforest Exhibit at the California Academy of Sciences Timothy Wong Biologist II, Steinhart Aquarium, California Academy of Sciences 55 Music Concourse Drive, San Francisco, CA 94118 The Osher Rainforest exhibit at the California Academy of Sciences houses a mixed species display of birds, butterflies, tropical plants, reptiles, fish, and amphibians in a spherical glass greenhouse. The exhibit was designed to house a diverse and naturalistic selection of species originating from rainforest habitats around the world; providing unique challenges for husbandry staff to successfully display a diverse selection of tropical Lepidoptera with insectivorous Passerine species chosen for exhibit. Photo 1: Paradise Tanager Tangara chilensis Photo 2: Heliconius hecale nectaring ​ ​ ​ ​ ​ Introduction Displaying live tropical butterflies successfully with insectivorous birds naturally poses many challenges. Since opening in 2008, the species of exhibit butterflies remained relatively unchanged resulting in regular predation and fewer butterflies on display. In 2017, the exhibit underwent significant renovations to improve how visitors experienced live butterflies, creating opportunities to make changes to husbandry, improve the habitat, and try new species of butterflies at elevated numbers while maintaining compatibility with the existing bird collection. These changes aimed to increase the survivability and maximize the diversity of butterflies on display. New feeding

(Dani Lopez-Velasco) SURINAME 23 FEBRUARY – 9/14 MARCH 2015 LEADER: DANI LOPEZ VELASCO and SEAN DILROSUN On our third tour to Suriname we amassed a great list of Guianan specialities, next to a splendid selection of more widespread, but rarely seen species. Our intrepid group recorded 404 species of birds, 16 mammals and some lovely ‘herps’ in this little country with its surface of about eight times Wales and its population of just over half a million people. We visited five different areas comprising three distinct ecosystems. It started with a short visit to the white sand grasslands and scrub of central Suriname where Black-faced Hawk, Bronzy Jacamar, Point-tailed Palmcreeper, Saffron-crested Tyrant–Manakin, Black Manakin and Glossy- backed Becard grabbed our attention. It continued with the famous Raleigh Falls and the Voltzberg, where many Guianan Cocks-of-the-Rock put on an unforgettable show on their lek, while other major avian highlights included brilliant Pompadour Cotingas, massive Black-throated and the very localized Band-tailed 1 BirdQuest Tour Report: Suriname www.birdquest-tours.com Antshrikes and delightful Red-billed Pied Tanagers. The misty forests of the Brownsberg were lighted up by incredibly tame Grey-winged Trumpeters and Black Curassows, rare Racket-tailed and stunning Tufted Coquettes, gaudy Blue-backed Tanagers and delicate White-fronted Manakins, colorful Rose-breasted Chats and much wanted Red-and black Grosbeaks.

    Molecular Phylogenetics of a Clade of Lowland Tanagers: Implications for Avian Participation in the Great American Interchange

MOLECULAR PHYLOGENETICS OF A CLADE OF LOWLAND TANAGERS: IMPLICATIONS FOR AVIAN PARTICIPATION IN THE GREAT AMERICAN INTERCHANGE KEVIN J. BURNS1 AND RACHEL A. RACICOT2 Department of Biology, San Diego State University, 5500 Campanile Drive, San Diego, California 92182, USA Abstract.—The importance of the formation of the Panamanian land bridge for mammalian diversification in the New World is well documented; however, studies investigating the role of this land bridge in avian diversification have only recently been reported. We used mitochondrial DNA data to reconstruct the phylogeny of a group of lowland tanagers (Thraupidae) that contains species distributed in both Central America and South America. Phylogenetic analyses identified a clade that includes all species in the genera Tachyphonus, Ramphocelus, Eucometis, Lanio, Trichothraupis, Coryphospingus, and Rhodospingus. Three of these species (Rhodospingus cruentus, Coryphospingus cucullatus, and C. pileatus) have traditionally been classified with the finches (Emberizidae); here, we show that they are tanagers. The genusTachyphonus is polyphyletic, with some species more closely related to species in the genus Ramphocelus than they are to other Tachyphonus. The ancestor of the entire clade was distributed in South America or was widespread there and in Central America. Reconstructing the biogeographic history of this group showed a dispersal bias from South America to Central America. Nine dispersal events were inferred, and eight of these involve dispersals from South America to Central America. Temporally, most dispersal events coincide with or postdate the final formation of the Panamanian isthmus. We also used our phylogeny to investigate plumage evolution.

Dan Webster Hanover College Hanover, Indiana 47243 ABSTRACT: There are 248 species of tanagers ( Aves, Pas- seriformes, Thraupinae) arranged in 61 genera and known chiefly from their skins. The author studied 434 skeletons of 191 species of 57 genera, describing the shape or measuring 36 characters on each. Twenty-three characters proved useful in generic discrimination. Presence or absence of a free lac- rimal; presence or absence of a manubrium-sternum bridge; shape and size of the interpalatine process; and the tibiotar- sus/ulna length ratio were the best discriminants. The phy- logeny of the tanagers remains unclear. More specimens must be studied. INTRODUCTION The 248 species of tanagers (Passeriformes, Emberizidae, Thraupinae) con- stitute a large, varied, colorful subfamily of neotropical birds. The last systematist to list all the known genera and species with their characters was Sclater (1886). Ridgway (1902) differentiated all the genera and those species found in North and Central American and the West Indies. Storer discussed the classification (1969) and listed all the forms (1970). Other important contributions were by Wetmore (1914), who described the peculiar stomach ofEuphonia, and by Beecher (1951), who stated, mainly on the basis of jaw muscles, that several genera of honeycreepers belonged with the tanagers. Lucas (1894) and Bock (1985) differ- entiated genera of honeycreepers on the basis of tongue structure. Sibley (1970) studied the egg white proteins of 7 genera. Raikow (1978, 1985) devised a clas- sification based mainly on the appendicular myology of 13 genera plus 4 borderline genera.

It sits atop 900-foot Semaphore Hill overlooking Soberania National Park. While its rooms are rather spartan, the food is Panama’s Canopy Tower © Ruthie Stearns excellent and the opportunity to view birds at dawn from the 360º rooftop Observation Deck above the treetops is outstanding. Twenty minutes away is the start of the famous Pipeline Road, possibly one of the best birding roads in Central and South America. From our base, daily birding outings are made to various locations in Central Panama, which vary from the primary forest around the tower, to huge mudflats near Panama City and, finally, to cool Cerro Azul and Cerro Jefe forest. An enticing example of what awaits visitors to this marvelous birding paradise can be found in excerpts taken from the Journal I write during every tour and later e- mail to participants. These are taken from my 17-page, January 2019 Journal. On our first day at Canopy Tower, with 5 of the 8 participants having arrived, we were touring the Observation Deck on top of Canopy Tower when Ruthie looked up and called my attention to a bird flying in our direction...it was a Black Hawk-Eagle! I called down to others on the floor below and we watched it disappear into the distant clouds.
