- Abstract
The present study deals with biological and trophic ecology of the Yellowlegged Gull, Larus michahellis, during the breeding period. It was carried out in the urban area of Tigzirt, a city located 40 km from Tizi Ouzou. The bioecological study of 20 nests occupied during the period from February to June provided an opportunity to record the external and internal dimensions of the nests, which were 50.4 ± 5.52 cm and 31.8 ± 4.70 cm, respectively. The inter-nest distance showed great variation, with an average of 9.91 ± 4.20 m. The clutch size was 2.13 ± 0.62 eggs/nest. The first clutches were noted as early as 4 March. Reproductive success was 2.2 at the egg stage and 1.36 at the chick stage. The study of the diet was carried out by analysis of 74 pellets. These were collected during the breeding season (March to May) in 2017. In March, the most consumed category was inorganic waste (55.56%), followed by vegetable waste (16.67%), terrestrial invertebrates (12.96%) and terrestrial vertebrates (12.96%). The other categories were poorly represented. In April, the most consumed category was inorganic waste (36.05%), followed by terrestrial vertebrates (22.09%) and terrestrial invertebrates (20.93%). The other categories are little consumed. In May, the most consumed categories were terrestrial vertebrates (29.41%), followed by inorganic waste (26.47%) and terrestrial invertebrates (26.47%). The other categories were poorly represented.
