the feather mites of the family proctophyllodidae (acari, sarcoptiformes) from nepalese birds.eight species of birds of the families fringillidae (3), motacillidae (2), prunellidae (1), pycnonotidae (1) and turdidae (1) were found to be parasitized by 8 species of the genus proctophyllodes, 3 of them being new to science: p. danieli sp. n. from pycnonotus leucogenys, p. macrophallus sp. n. from prunella collaris and p. puniceus sp. n. from pyrrhospiza punicea. other species recorded are p. anthi, p. cotyledon, p. glandarinus, p. leucosticti and p. aff. poublani. all hosts were collected ...19883198015
spermiophagy in the male reproductive tract of some passerine order to elucidate the locus and means of spermiophagy in passerine birds, we examined histologically the entire male reproductive tract of sexually mature birds of three passerine species with different forms of sperm competition, namely, the alpine accentor (prunella collaris), the redflanked bush robin (tarsiger cyanurus), and the bengalese finch (lonchura striata var. domestica). spermiophagy occurred consistently and frequently in the epithelial layer of the seminal glomera and ejaculato ...201121882958
multiple mating and cooperative breeding in polygynandrous alpine accentors. ii. male mating tacticsi studied the timing and frequency of male copulatory behaviour in alpine accentors, prunella collaris, in japan, with respect to dominance status, age and development of the cloacal protuberance. males used one of three mating tactics depending on their dominance status. alpha males guarded several females in succession, but only during the females' fertile period, while gamma males copulated rarely and only with unguarded females. the tactics of beta males were flexible: with unguarded females ...19989480695
multiple mating and cooperative breeding in polygynandrous alpine accentors. i. competition among femalesthe reproductive strategy of female alpine accentors, prunella collaris, was studied on the summit of mt norikura in japan. alpine accentors formed polygynandrous groups consisting of three to six males and three to five females; however, each female laid eggs in her own nest. within each group, females were organized in stable, linear hierarchies based on age. all females were sexually active but high-ranking females copulated more frequently with several males from the group. in contrast, the ...19989480694
alpine accentors as monitors of atmospheric long-range lead and mercury pollution in alpine environments.mercury and lead are deposited in the west carpathians as long-range transported air pollution. the alpine accentor (prunella collaris) was recognized as a cost-effective biomonitor, and used to investigate the bioavailability of contaminants in large alpine areas. the outer tail feathers and blood of the alpine accentors were used for assessment of atmospheric mercury and lead contamination, respectively. mean mercury levels in feathers of accentors averaged at 1.15 μg/g (se = 0.105, n = 40). t ...201930471058
