No, birds do not have periods. Periods are a monthly shedding of the uterine lining in humans and other mammals. Birds do not have a uterus, so they cannot have periods. Instead, birds lay eggs. When a bird ovulates, an egg is released from her ovary and travels down her oviduct. The egg is then fertilized by a sperm cell and incubated in the oviduct until it hatches.

Some people may mistakenly think that birds have periods because they see blood around a bird's nest. However, this blood is not from a period. It is from the bird's cloaca, which is a common opening for both the reproductive and digestive systems. When a bird lays an egg, it can sometimes rupture the lining of the cloaca and cause bleeding. This is not a serious condition and usually heals on its own.
