![]() Adults also feed on ephemeral outbreaks of tent caterpillars and their pupae (Lasiocampidae: Malocosoma spp. Percentage composition by number indicates consistent year-to-year use of certain orders (Lepidoptera, Orthoptera) but fluctuation in others (e.g., Coleoptera) ( 57 Flocks often return to good foraging areas on successive days ( 5įeeds almost exclusively on a wide variety of ground-dwelling invertebrates, including those within top soil or under objects (cryptozoa), those that walk on ground, and those that live or rest above ground in grass ( 57ĭuring breeding season, feeds a wide variety of insects to nestlings (62 different families 57 Feeding more restricted to ground and searches less from perches than California Scrub-Jay ( Aphelocoma californica) ( 57 Pounces on small mammals from a perch, then kills them with bill (MDR) or, occasionally, drowns them ( 58īlackburn, C. Hunts grasshoppers on ground in grass cover or gleans them from grass leaves and seed heads. chasing ground prey, flicking litter with bill, and flycatching ( 57 Uses a variety of feeding methods, including pecking at food that is picked off the ground, holding prey with feet and pecking at it, turning over ‘cow-pies’ and large fallen deciduous leaves. Obtains most food by picking up items from, or just below, surface of ground. Forages on ground in small flocks in breeding season, and in large flocks in non-breeding season. Will exploit areas with sudden high groundwater, following heavy rain, which drives worms and insects to the surface ( 5įoraging methods similar to those of other open-country corvids. Yellow-billed Magpie population status and habitat characteristics in urban Sacramento, California. In urban and suburban Sacramento in the Central Valley, forages selectively on irrigated turf areas, especially those more lightly maintained with accumulations of large deciduous leaves, and in areas of annual grassland that is mowed or grazed, and avoids developed and wooded areas ( 10Īirola, D. Prefers foraging in short vegetation of grazed rather than ungrazed pasture ( 5 Daily and annual time budget of the Yellow-billed Magpie. During hot summer months, foraging restricted to early morning and late afternoon ( 57 ![]() Most foraging on ground in savanna grassland, pasture, agricultural areas, and barnyards, to a lesser extent in oak understory and in mid canopy of trees. Occasionally feeds on pet food at feral cat feeding stations and at trash cans (DAA). ![]() The ecology of spacing behavior in the Yellow-billed Magpie Pica nuttalli.
