What do storks legs do?
Turkey vultures defecate on their legs in order to cool themselves. The water in the waste evaporates, lowering the temperature in the legs, and the cooled blood travels back through the rest of the body. Storks also do this, a practice known as urohidrosis. Because birds can't sweat, this is their only substitute.
April is the time of year when the storks (Ciconiidae family) arrive in Latvia. Specifically, Latvia is a popular destination for the storks of African origin. It is estimated that about six times as many storks visit Latvia as any other Western European country. The annual count may number as much as 6,000 to 7,000. Farmers often welcome storks by placing cart wheels on poles or trees to accommodate stork nest building activities.
