Gulls are the most numerous kind of birds from the family of gulls.They live on the sea space, and in inland waters.As a rule, a seagull - a bird medium or large size.Plumage they usually white or gray, often have wings on my head, or black marks.A distinctive feature of these birds can be called well-developed swimming membrane on the feet and beak, which is slightly curved at the end.
gull chicks appear well furred and with their eyes open already.These spotted lumps did not look like their parents.For a time, they are in the nest under their supervision.A few hours after the birth of the chicks of gulls are beginning to demand food.For their parents, they are unrecognizable only a few days after birth, then each parent unerringly finds his chick.By the way, do you know the name of a seagull chick?In the dictionary Dahl young gull (chick) is Chabar.And here at the Danilovsky chabor - a hard-set in the egg, but not hatchling.
Gulls not only able to nurse their young - they can take and strangers, but only up to 14 days.In breeding colonies adopt most often occurs under certain conditions.For example, when the panic caused by the appearance of a predator or visiting rights.It may also be due to unfavorable climatic conditions.
most mass adoption occurs in Franklin gulls, which nest in the marshes.They build their nests of reeds and water while lifting many nests float, because they can not gain a foothold.Young chicks of gulls Franklin at this time often leave the nest to go for a swim.And each of them can climb in any slot, which will be adopted by adult birds to their brood.
And here at the gray gulls that breed in Chile in a hot desert, the situation is somewhat different.Adult birds are on the nests and their bodies provide shade.Anyone can come gull chick to the nest where it fed and will hide from the sun.But if he will be away from the nest, the adult gulls will be attacked and even their parents.
must say that gulls tend angry behavior.And their anger is always directed toward the young.This is especially true for males.They often attack the chicks are close to them or run past fit.During these attacks gull chicks often die, and this somehow be justified if they are then used as feed.But no, this is not happening.So males attacking stray chicks just because they are descendants of other gulls.For example, broody intraspecific predation has a "domino effect".If out of the nest someone steals chick or the egg, the egg will steal an irate male (or chicks) from another pair and so on.
colonial gulls have developed communal care of their offspring.This phenomenon can occur spontaneously due to predators.The chicks gather in large groups - nurseries, which are protected by adult birds.The formation of such nurseries helps seagulls to defend their offspring from attack by crows, rats and other predators.They can also be grouped together, if the colony bother people.Some adult birds is to protect the young and the remaining collectively distilled stranger or predator attack from above.
