Of Extinct Rebuilding the Socorro Dove Population by Peter Shannon, Rio Grande Zoo Curator of Birds
B BIO VIEW Curator Notes From the Brink of Extinct Rebuilding the Socorro Dove Population by Peter Shannon, Rio Grande Zoo Curator of Birds In terms of conservation efforts, the Rio Grande Zoo is a rare breed in its own right, using its expertise to preserve and breed species whose numbers have dwindled to almost nothing both in the wild and in captivity. Recently, we took charge of a little over one-tenth of the entire world’s population of Socorro doves which have been officially extinct in the wild since 1978 and are now represented by only 100 genetically pure captive individuals that have been carefully preserved in European institutions. Of these 100 unique birds, 13 of them are now here at RGZ, making us the only holding facility in North America for this species and the beginning of this continent’s population for them. After spending a month in quarantine, the birds arrived safe and sound on November 18 from the Edinburgh and Paignton Zoos in England. Other doves have been kept in private aviaries in California, but have been hybridized with the closely related mourning dove, so are not genetically pure. History and Background Socorro doves were once common on Socorro Island, the largest of the four islands making up the Revillagigedo Archipelago in the East- ern Pacific ocean about 430 miles due west of Manzanillo, Mexico and 290 miles south of the tip of Baja, California. Although the doves were first described by 19th century American naturalist Andrew Jackson Grayson, virtually nothing is known about their breeding behavior in the wild.

Mimus Gilvus (Tropical Mockingbird) Family: Mimidae (Mockingbirds) Order: Passeriformes (Perching Birds) Class: Aves (Birds)
UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour Mimus gilvus (Tropical Mockingbird) Family: Mimidae (Mockingbirds) Order: Passeriformes (Perching Birds) Class: Aves (Birds) Fig. 1. Tropical mockingbird, Mimus gilvus. [http://asawright.org/wp-content/uploads/2012/07/Tropical-Mockingbird.jpg, downloaded 16 November 2014] TRAITS. The tropical mockingbird is a songbird that can be identified by its ashy colour; grey body upperparts and white underparts. It has long legs, blackish wings with white bars and a long blackish tail with white edges. The juvenile is duller and browner than adults with a chest slightly spotted brown. The average length and weight of the bird is 23-25cm and 54g respectively (Hoyo Calduch et al., 2005). It has yellow eyes and a short, slender, slightly curved black bill. There is no apparent sexual dimorphism (Soberanes-González et al., 2010). It is the neotropical counterpart to the northern mockingbird (Mimus polyglottos), with its main difference being that the tropical mockingbird has less white in its wings and primaries (flight feathers). ECOLOGY. Mimus gilvus is found in open habitats ranging from savanna or farmland to human habitation. These birds are geographically distributed from southern Mexico to northern South America to coastal Eastern Brazil and the Southern Lesser Antilles, including Trinidad and Tobago (Coelho et al., 2011). The tropical mockingbird may have been introduced into Trinidad UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour and Panama, but these are now resident populations. It builds its cup-like nest in thick bushes or shrubbery with sticks and roots about 2-3m off the ground (Hoyo Calduch et al., 2005).

Gray Catbird, Northern Mockingbird and Brown Thrasher
Wildlife Note — 51 LDR0103 Gray Catbird, Northern Mockingbird and Brown Thrasher by Chuck Fergus Gray Catbird These three species are among the most vocal of our birds. All belong to Family Mimidae, the “mimic thrushes,” or “mimids,” and they often imitate the calls of other spe- cies, stringing these remembered vocalizations into long, variable songs. Family Mimidae has more than 30 spe- cies, which are found only in the New World, with most inhabiting the tropics. The mimids have long tails and short, rounded wings. The three species in the Northeast are solitary (living singly, in pairs and in family groups rather than in flocks), feed mainly on the ground and in shrubs, and generally eat insects in summer and fruits in winter. The sexes look alike. Adults are preyed upon by owls, hawks, foxes and house cats, and their nests may be raided by snakes, blue jays, crows, grackles, raccoons, opossums and squirrels.

Breeding Season Diet of the Floreana Mockingbird (Mimus Trifasciatus), a Micro-Endemic Species from the Galápagos Islands, Ecuador
196 Notornis, 2014, Vol. 61: 196-199 0029-4470 © The Ornithological Society of New Zealand Inc. Breeding season diet of the Floreana mockingbird (Mimus trifasciatus), a micro-endemic species from the Galápagos Islands, Ecuador LUIS ORTIZ-CATEDRAL Ecology and Conservation Group, Institute of Natural and Mathematical Sciences, Massey University, Private Bag 102-904, Auckland, New Zealand Abstract I conducted observations on the diet of the Floreana mockingbird (Mimus trifasciatus) during its breeding season in February and March 2011. The Floreana mockingbird is a critically endangered species restricted to Gardner and Champion Islets off the coast of Floreana Island, in the Galápagos Islands, Ecuador. During 11 days, 172 feeding bouts of adult and nestling mockingbirds were observed. The majority of feeding bouts of adults (31%; 19 feeding bouts) involved the consumption of nectar and pollen of Opuntia megasperma. Another important food item consisted of Lepidopteran caterpillars (27%; 17 feeding bouts). The majority of food items fed to nestlings consisted of Lepidopteran caterpillars (26%; 29 observations), followed by adult spiders (19%; 21 observations). The reintroduction of the species to its historical range on Floreana Island is currently being planned with an emphasis on the control or eradication of invasive cats and rats. To identify key areas for reintroduction, a study on the year-round diet of the species as well as availability and variability of food items is recommended. Nectar and pollen of Opuntia megasperma was an important dietary item for the species during its breeding season. This slow-growing plant species was widespread on the lowlands of Floreana Island but introduced grazers removed Opuntia from most of its range.

E‑mail: [email protected] Recebido em 20 de janeiro de 2007; aceito em 11 de maio de 2007. RESUMO: Como uma minhoca: o sabiá-do-campo (Mimus saturninus) mata e ingere uma cobra d’água juvenil. Diversas espécies de Passeriformes neotropicais apresam vertebrados, embora serpentes sejam presas raramente registradas. Apresento aqui um registro de sabiá‑do‑campo (Mimus saturninus) apresando uma cobra‑d’água juvenil. Uma vez que serpentes são presas perigosas, é aqui proposta a hipótese de que serpentes apresadas por Passeriformes sejam principalmente juvenis de espécies não‑venenosas e não‑constritoras. Também, sugiro que o apresamento de serpentes de pequeno porte e relativamente inofensivas representa uma alteração simples no comportamento de caça de Passeriformes que tenham o hábito de apresar minhocas e artrópodes alongados como lagartas e diplópodes. PALAVRAS-CHAVE: Ofiofagia, comportamento predatório, presas alongadas.

1 Why Mockingbird Speciation in the Galapagos
1 WHY MOCKINGBIRD SPECIATION IN THE GALAPAGOS ARCHIPELAGO IS LIMITED TO FOUR SPECIES ERIKA HARRELL DARWIN, EVOLUTION, AND GALAPAGOS DURHAM OCTOBER 2008 2 Introduction The central question of this study is why mockingbird speciation in the Galapagos is limited to only four species. The answer to this question is significant becauses it pertains to the broader question of what characters of a species or environment make for less selective pressures and more limited speciation and what characters of a species/environment selectively pressure for greater speciation. It also addresses the question of how specific characters of a species and an environment can interact to selectively pressure for broad or limited speciation. I chose to study these questions by observing the mockingbirds of Galapagos because these birds not only exhibit limited speciation, but can conveniently be compared to the finches of the Galapagos, which have speciated significantly more than the mockingbirds. Advantageously, both sets of species are confined to the Galapagos archipelago and experience much habitat overlap. Therefore, by comparing them, it is easy to determine what characters of each and of their environment pressured for or against extreme speciation. My primary hypothesis is that mockingbirds are resourceful generalists and omnivores, so there was no selective pressure on these birds to split into specialists with regard to food consumption. Finches, on the other hand, have a diet that is restricted by the fact that they are chiefly herbivores. Such a restriction is a signicant selective pressure that the mockingbirds simply did not have. To test my hypothesis, I considered experimentation and data gathered by accomplished researchers, and observed the different species of both mockingbirds and finches in the Galapagos wild.

A Field Study of the Mockingbird's Wing-Flashing Behavior and Its Association with Foraging
A FIELD STUDY OF THE MOCKINGBIRDS’ WING-FLASHING BEHAVIOR AND ITS ASSOCIATION WITH FORAGING BY JACK P. HAILMAN HE peculiar “wing-flashing” behavior of the Mockingbird (Mimus poly- T glottos) has been the subject of much study and discussion among American field workers, and yet there is little agreement on the biological function of this behavior. The most prevalent theory, perhaps, is that the motions are associated with hunting insects (e.g., Gander, 1931; Hebard, 1949a, 19496; Wampole, 1949; Brackbill, 1951). However, Sutton (1946) believed that wing-flashing is an alarm reaction, because several observers reported it when birds were confronted with strange objects or situations (e.g., Michener and Michener, 1935:106; Laskey, in Sutton, 1946; and Sut- ton, 1946). Recently Brackbill (p ers. comm.) has come to believe that the behavior is produced by hostile or fear motivation. Others have termed wing- flashing a sexual display (Forbush, 1929:320), and one observer (Tomkins, 1950) concluded that “it has no present value to the species.” Disagreement concerning the form of the behavior as well as its function has arisen. Suttons’ (1946) painting shows a Mockingbird with its wings held high above its back, but Wampole (1949) describes the wings as being moved horizontally. Many authors do not describe the motions they call “wing-flashing.” METHODS Field observations were made from June to August, 1958, at eight locali- ties in the suburbs of Washington, D.C., and from April to July, 1959, in Norfolk, Virginia. The 1959 study was of adults only, since it was terminated before general fledging time, and involved only about three pairs of birds; the 1958 observations were of both young and adults.

Northern mockingbird, Mimus polyglottos. [http://ibc.lynxeds.com/photo/northern-mockingbird-mimus-polyglottos/perched-showing-large-white-wing-patch downloaded 7 November 2012] TRAITS. The northern mockingbird is a songbird which can be identified by its upper part of the body being either grey or grey-brown and the lower parts of its body being white or grey (Doughty 1988). The total length of females would usually be 208-235 mm, whereas the males would typically be 220-255 mm. The northern mockingbird has short wings that are rounded in shape and it has a long tail, as well as long legs. White narrow bars can be found on its wings, as well as a patch of white colour (Derrickson et al. 1992). Its head is small and on it is a thin, short, black-coloured bill that is curved to a small extent. Juveniles have similarities to the adult, except that they have slightly spotted breasts (Dunne, 2006). UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour ECOLOGY. The northern mockingbird is found in habitats ranging from open woodland, suburban lots, parks and farmland. They are typically found in the United States, southern Canada, Mexico and the Greater Antilles (Mobley, 2009). They are an accidental visitor to Trinidad, where the tropical mockingbird M. gilvus is the common resident species of mockingbird. Their food consists of seeds, insects and berries, which may be found either in vegetation or on the ground.
