Ecosystem and habitat
The yellow-billed blue magpie species have moderate forest dependence. They normally occur in altitudes from 1600 to 2700 meters.The artificial ecosystems and habitats of these species include agricultural lands, plantations and heavily degraded tropical and subtropical forests.
The natural ecosystems and habitats of these yellow-billed blue magpie species include tropical and subtropical moist lowland forests, foothill forests, temperate forests and moist montane forests.
Diet and feeding behavior
The diet of this yellow-billed blue magpie species consists mainly of invertebrates. Insects, small mammals, eggs and hatchlings of birds, wild fruits and berries are their primary food.These magpies are mostly arboreal and sometimes they feed on the ground by adopting a hopping gait, with the tail held high.
Reproduction and breeding habits
The breeding season of these yellow-billed blue magpie species is from April to July in most of their breeding range. These species are monogamous and territorial.The nesting sites include fork of tree branches. The magpie nest is a cup of twigs and sticks, lined with grass, rootlets and plant fiber. The clutch contains 3-4 pale colored eggs, with small specks, blotches and streaks.
Migration and movement patterns
These yellow-billed blue magpie species are non-migratory resident birds. The populations in higher altitudes descend to lower levels in winter.Post breeding, the juvenile magpies may disperse and establish in new locations within the range. Within their range they may make local movements for feeding and breeding.
