INFESTASI KUTU PADA AYAM KAMPUNG (Gallus gallus domestic) DI DESA TOLOK KECAMATAN TOMPASO KABUPATEN MINAHASA

LOUSE INFESTATION AT LOCAL LAYING HENS (Gallus gallus domestic) AT TOLOKVILLAGE TOMPASO DISTRICT OF MINAHASA REGENCY. The objective of this study was to count the infestation, preference of this louse on parts of the body and sex of birds, The purposive random sampling method was used in sample collection implemented manually on the birds stated in the morning and in the afternoon by screening all body of birds initiated from head, neck, hip, abdomen, thigh, and tail using all fingers. Samples of louses found were filled into bottle containing alcohol of 70%. Samples of louses were counted. Result showed that the parasite found one type of louse (Menopon gallinae) with preference infestation of 87.5% from 40 local laying hens spreading on the body parts of birds in the average frequencies on hip of birds about 6.23 louses/bird, on neck of bird about 3.43 louse/bird, on abdomen of bird about 5.48 louses/bird, on thigh about 0.83 louses/bird and on tail about 1.28 louses/bird. The preference of parasite was found on female bird with the average of 20.35 louses/female bird and 14.10 louse/male bird. Key words: Infestation, louses, local laying hens.

New insights from female bird song: towards an integrated approach to studying male and female communication roles

Historically, bird song has been regarded as a sex-specific signalling trait; males sing to attract females and females drive the evolution of signal exaggeration by preferring males with ever more complex songs. This view provides no functional role for female song. Historic geographical research biases generalized pronounced sex differences of phylogenetically derived northern temperate zone songbirds to all songbirds. However, we now know that female song is common and that both sexes probably sang in the ancestor of modern songbirds. This calls for research on adaptive explanations and mechanisms regulating female song, and a reassessment of questions and approaches to identify selection pressures driving song elaboration in both sexes and subsequent loss of female song in some clades. In this short review and perspective we highlight newly emerging questions and propose a research framework to investigate female song and song sex differences across species. We encourage experimental tests of mechanism, ontogeny, and function integrated with comparative evolutionary analyses. Moreover, we discuss the wider implications of female bird song research for our understanding of male and female communication roles.

SIFAT KUALITATIF, MORFOMETRIK, DAN KARKAS BURUNG AYAMAN (Gallirallus phillippensis) DI KAMPUNG MACUAN DISTRIK MASNI KABUPATEN MANOKWARI

Ayaman bird (Gallirallusphilippensis) usually hunted for meat for people in Prafi, specifically in Macuan village. The aim of this research was to determine the qualitative, morphometric measurement, carcass quality and meat nutritional contain of Ayaman bird. Fifty six head of ayaman birds (28 males and 28 females) was used in this research. Descriptive method with case study technique was used. Data was analyzed with t test. Qualitative trait such as feather color, shank shape were the same between male and female bird except for the color of the beak and shank were different. Male and female beak and wings length were not significantly different, while tail and middle finger of the male were longer than the female bird. Carcass, hind and fore carcassweight were heavier in male than female bird, but carcass percentage were the same between male and female bird. Meat nutritional contain such as protein, fat, energy and cholesterol were the same between male and female bird.
