TIME AND ENERGY BUDGETS OF THE MOCKINGBIRD (MIMUS POLYGLOTTOS) DURING THE BREEDING SEASON

Tropical Mockingbird (Mimus gilvus) Science Article 2 abstract A time and energy budget of male and female Mockingbirds (Mimus polyglottos) in six phases of their breeding cycle was completed using the equivalent temperature model to predict perching metabolic rates. Recorded time-budget behaviors included perching, bipedal locomotion, flight, and the time spent in the sun and […]

New records concerning range and altitudinal distribution ofTropical Mockingbird Mimus gilvus in Ecuador

Tropical Mockingbird (Mimus gilvus) Science Article 4 abstract Se reportan dos nuevas localidades para el Sinsonte Colilargo Mimus gilvus en Ecuador. Junto aestos registros la especie es conocida por cuatro observaciones en el pais, todas ubicadas en losAndes del norte de Ecuador. Se sugiere que Mimus gilvus puede estar extendiendo su rango dedistribucion desde Colombia, […]

PREDATION BY GRAY CATBIRD ON BROWN THRASHER EGGS

Grey Catbird (Dumetella carolinensis) Science Article 3 abstract The gray catbird (Dumetella carolinensis) has been documented visiting and breakingthe eggs of artificial nests, but the implications of such observations are unclear because there is little cost in depredating an undefended nest. During the summer of 2001 at Konza Prairie Biological Station, Kansas, we videotaped a […]

Documentation of a Polygynous Gray Catbird

Grey Catbird (Dumetella carolinensis) Science Article 2 abstract Polygyny occasionally occurs in passerine species that are generally socially monogamous.We document the second case of polygynous mating in the Gray Catbird (Dumetella carolinensis) and provide the first detailed account of this behavior.

PATTERNS OF HaeMOPROTEUS BECKERI PARASITISM IN THEGRAY CATBIRD (DUMATELLA CAROLINENSIS) DURING THEBREEDING SEASON

Grey Catbird (Dumetella carolinensis) Science Article 4 abstract We determined the prevalence and intensity of blood parasites in breeding graycatbirds (Dumatella carolinensis) at Killbuck Wildlife Area in Wayne and Holmes Counties, Ohio(USA) from June through August 2000. Of 98 catbirds sampled, 40 (40.8%) had detectableinfections of Haemoproteus beckeri. Overall prevalence of H. beckeri in this […]

THE BREEDING STATUS OF THE GRAY CATBIRD IN FLORIDA

Grey Catbird (Dumetella carolinensis) Science Article 5 abstract Although Howell (1932) stated that the Gray Catbird (Dumetella carolinensis) ‘breeds sparingly in northern and central Florida,’ some recent field workers in this state have viewed his statement skeptically. Of Howell’s seven references to Florida breeding, four were made by Oscar Baynard, some of whose records of’ […]

Song learning in birds: diversity and plasticity, opportunities and challenges

Brown Thrasher (Toxostoma rufum) Science Article 10 abstract A common trend in neuroscience is convergence on selected model systems. Underlying this approach is an often implicit assumption that mechanisms observed in one species are characteristic of all related species. Although themodel systemapproach has been extremelyproductive, itmight not account for all of themechanistic differences between species […]
