Measurement of Complacency in Blackbirds
نویسنده
چکیده
The complacency—agitation continuum in Blackbirds was studied by recording their behavior in an observation cage. A scoring pattern with a reliability of 0.91 was developed. Cowbirds are the most complacent species and Starlings the most agitated. Grackles and Red-wings are intermediate. Individual differences within each species are demonstrated. It is probable that the trait under investigation is composed of a number of factors and that a factor analysis of several tests like the present one will throw light on avian personality structure.

Absorption, distribution, and excretion of [14C]-3-chloro-4-methylaniline hydrochloride in two species of birds following a single oral dose.
Ring-labeled [14C]-3-chloro-4-methylaniline hydrochloride (250 microg per bird) was delivered to 21 red-winged blackbirds (Agelaius phoeniceus) and 21 dark-eyed juncos (Junco hyemalis) via oral gavage, and the distribution and excretion of radioactivity were determined at 15 and 30 min and 1, 4, 8, 12, and 24 h (n = 3 per time point). Direct measurement of radioactivity as well as measurement f...
متن کاملResponses of Caged Red-winged Blackbirds to Methiocarb on Wild Rice
Red-winged blackbirds (Agelaius phoeniceus) were offered a choice between cultivated wild rice (Zizania aquatica) treated with methiocarb and untreated wild rice. Unhulled wild rice soaked in methiocarb solution was highly effective in repelling blackbirds at residue levels <132 ppm. The responses of blackbirds to methiocarb residues <132 ppm on soaked rice were variable. Most of the blackbirds...

متن کاملThe role of blackbirds (Turdus merula) in weed invasion in New Zealand
The naturalised European blackbird (Turdus merula) is the most widely distributed avian seed disperser in New Zealand. Together with the native silvereye (Zosterops lateralis) they are the major seed dispersers over large areas of New Zealand. I review the international literature on aspects of the ecology and behaviour of blackbirds relevant to their potential for dispersing weeds in New Zeala...
متن کاملEvaluation of elevated bait trays for attracting blackbirds (Icteridae) in central North Dakota
Sunflower (Helianthus annuus L.) became an economically important crop in North Dakota in the 1970s, providing a major source of food for post-breeding blackbirds (Icteridae). Reducing local blackbird populations with rice grains treated with an avicide is one proposed alternative for reducing sunflower damage. In fall 2007 and 2008, we evaluated the idea of attracting blackbirds to rice-baited...
