Should a bird's nest appear before you on the way, on any tree or on the earth, chicks or eggs, and the mother resting on the chicks or the eggs: You shall not take the mother with the offspring. You shall send away the mother, and take the offspring for yourself, so that it be good for you, and your days be long.
The nest aggregation of thousands of colonies that persists throughout the year becomes a lek mating system on warm summer days in the latter half of the breeding season (July through September). The daily operational sex ratio has far more males than females, which is common in a lek mating system and among other bees. [ 7 ]

Village weavers nest in colonies and are very active during the breeding season. Birds fly in and leave again constantly, making significant noise. Colonies can contain as many as 150 nests, but eight to a hundred nests in a single tree are usual. [10] A village weaver's nest is 14–17 cm (5.5–6.7 in) long and 11–13 cm (4.3–5.1 in) high.
The common murre nests in densely packed colonies (known as "loomeries" [citation needed]), with up to twenty pairs occupying one square metre at peak season. [citation needed] Common murres do not make nests and lay their eggs on bare rock ledges, under rocks, or the ground. Despite the high density of murre breeding sites, sites may vary ...
Nesting season is in full swing as well. Hopefully our cliff swallows will be thriving along with many other nesting birds. Enjoy this wonderful time of the year and make time for the birds in ...
Trees and bushes are the preferred location for nests, the herons will usually build in high branches away from the trunk. A pair can use the same nest for years, enlarging it every season; the first nest is usually just large enough to hold the eggs. Nest-building is not the result of successful courtship, but rather an active part of the ...
It was found that nests close to cuckoo perches were most vulnerable: multiple parasitised nests were closest to the vantage points, and unparasitised nests were farthest away. Nearly all the nests "in close vicinity" to the vantage points were parasitised. More visible nests were more likely to be selected by the common cuckoos.
