Measurement of Complacency in Blackbirds
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 investigati...
متن کاملDevelopment of protein polymorphisms in redwing blackbirds.
Breeding populations of the redwing blackbird, Agelaius phoeniceus, were studied to compare protein differences during development. Proteins which represented a minimum of ten loci were studied in egg white, embryonic, nestling and adult tissue. In starch-gel electrophoresis at several conditions of pH only ovoglobulin, ovotransferrin and general esterases were polymorphic. Tissue specificity w...
متن کاملDevelopment of Seed Treatments to Control Blackbirds
Bird repellents to protect seeds are a potentially important aspect of integrated vertebrate pest management strategies. Yet, there currently are no repellents registered for seed treatment uses. This is due not to lack of effective candidate compounds, but to monetary and regulatory constraints that inhibit commercialization of promising compounds. Two examples of this dilemma are methiocarb a...
متن کاملA Comparative Study of Cowbird Parasitism in Yellow-headed Blackbirds and Red-winged Blackbirds
--We compared Yellow-headed Blackbirds (Xanthocephalus xanthocephalus) and Red-winged Blackbirds (Agelaius phoeniceus) to determine possible explanations for the lack of Brown-headed Cowbird (Molothrus ater) parasitism on Yellow-heads. Twenty-three cowbird eggs were cross-fostered from Red-winged Blackbird nests to Yellow-headed Blackbird nests. Eleven of the cross-fostered cowbird eggs hatched...
