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 ]
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.

Once they leave the nest, chicks follow their parents to the nearest water. Bonaparte's gulls begin breeding at two years of age; they are thought to be monogamous. [15] The breeding season begins in mid-June. [24] Courting pairs perform swooping display flights, calling loudly and diving at each other, and then drop down to perch on a branch.
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.
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 ...
Like many other aspects of its life, the yellow-crowned night heron's breeding season depends closely on the emergence of crabs in the spring; the crab cycle itself depends on temperatures. As such, the breeding season of the yellow-crowned night heron varies geographically, typically between March and May.
In species that exhibit lifelong monogamous pair bonds, even outside of the breeding season, there is no bias in the sex that is philopatric. [13] However, among polygynous species that disperse (including those that find only a single mate per breeding season), there is a much higher rate of breeding-site philopatry in males than females among ...
