The mud tile house is under, with eaves to shelter from the wind and rain, and a certain height from the ground, which will not be disturbed by human daily life. There is a low-lying quagmire near home, and mud is the first choice for swallows to nest. Where there is a quagmire, it is convenient for swallows to take local materials. The home is quiet and lively, and the host's house will not be maliciously destroyed. Small insects will gather in the low-lying water mire or garden grass, which is convenient for swallows to prey.
Because swallows often go out even if they don't brood, and they go out more frequently when they brood, they need a very convenient place to go in and out. There are usually 2-3 places to fly out. So even if one door is closed, they can go in and out through other exits.
Swallow nesting method
Swallows nest under the eaves of farmhouses. Most of these nests are made of saliva-bonded soil and grass stems, covered with soft weeds, feathers, rags and some Artemisia annua leaves. The bird's nest is dish-shaped. Nesting is mainly because the nest has a certain heat preservation effect to slow down the heat loss, which is beneficial to the growth and development of young chicks. The activity process of nesting behavior is helpful to stimulate physiological activities, so that eggs in the body can mature and be discharged quickly without interruption of reproductive behavior.
Swallows breed 2 nests every year, mostly from May to early June and from mid-June to early July. Each nest lays 4 ~ 6 eggs. The second nest is less, 2 ~ 5 pieces. Eggs are milky white. Males and females hatch eggs together. 14- 15 days, chicks hatch and parents eat together. The chicks fly out in about 20 days, and then feed them for 5 ~ 6 days, so they can feed themselves. The food is full of insects.
