The eggs are pale green, round, and flattened, with a diameter of about 0.5 millimetres (0.020 in). They are laid singly on buds and flowers of a food plant. The caterpillars are 0.7 centimetres (0.28 in) long, green with a dark red line along the back, and light and dark lines partway along the sides.
The nests in bushes often are a simple structure of twigs and vegetation that are often fragile. [10] They can become sexually active within 79 days after hatching. [12] Nesting can occur between February and October; however, the peak of nesting occurs between early April and mid May. [13] They can have 2–3 broods in any given year. On ...
The blue ground dove is relatively common in open woodland, forest edges, clearings and roadsides, especially in more humid areas. It is found from sea level to about 1200 m altitude. It builds a flimsy dish nest of twigs 1–11 m high in a tree and lays two white eggs.
The pigments biliverdin and its zinc chelate give a green or blue ground color, and protoporphyrin produces reds and browns as a ground color or as spotting. Non-passerines typically have white eggs, except in some ground-nesting groups, such as the Charadriiformes , sandgrouse and nightjars , where camouflage is necessary, and some parasitic ...
Construction of the nest is done primarily by the female and takes around 10 days to complete. These nests are small, cup-like structures lined with grass, feathers, stems, and hairs. Each female lays three to seven light-blue or, rarely, white eggs. The female incubates the eggs, which hatch after 13 to 16 days.
The colour of the eggs seems to have evolved through the relatively good visibility of blue at low light levels. [50] The egg size is 26.5–34.5 mm (1.04–1.36 in) in length and 20.0–22.5 mm (0.79–0.89 in) in maximum diameter. [15] Eggs, Collection Museum Wiesbaden, Germany
Pseudospinolia neglecta. Members of the largest subfamily, Chrysidinae, are the most familiar; they are generally kleptoparasites, laying their eggs in host nests, where their larvae consume the host egg or larva while it is still young, then the food provided by the host for its own juvenile.
The nest is usually placed in a hole in the ground, but rock faces and buildings are also used. This species will use nest boxes or a disused sociable weaver nest. The clutch is 2-4 greenish-blue eggs decorated with reddish-brown speckling. The eggs hatch after 13–15 days. The nestlings are fed by both parents and fledge after 13–15 days.
