Temporal and spatial patterns in the diet of the Common Murre in California waters

Article Abstract:

Study of temporal and spatial variations in the diet of the Common Murre, Uria aalge, in the coastal California waters shows that prey availability and foraging habitat influence the diets of these local breeding seabirds. Diets are most disparate during winter and El Nino periods. Euphausiids and juvenile rockfish are common in the diet during the pre-breeding season after the onset of updwelling. The diet of murres foraging in mid- and outer-shelf habitats comprises mainly of rockfish during the breeding season.

Female plumage coloration in the bluethroat: no evidence for an indicator of maternal quality

Article Abstract:

The female plumage character in the bluethroats (Luscinia svevica svevica) was investigated as an indicator of female parental quality and of success in reproductive performance. The degree of female coloration evaluated based on its relationship with the timing of breeding, zygotic investment, maternal effort and seasonal reproductive success. The results showed that plumage coloration does not reflect parental abilities in female bluethroats.

Extra-pair paternity in the Common Murre

Article Abstract:

Research is presented concerning the occurrence of extra-pair paternity in the Common Murre through the use of multi-locus DNA fingerprinting techniques. Extra-pair paternity was detected in 7.8% of families.
