The worm (Scientific name: Rostrhamus sociabilis ) is a bird of the eagle family . It is a medium-sized raptor with a body length of about 45 cm. The upper body feather is dark blue. The head and lower body feathers are grayish or variegated. Black claw tip, eyes brown red.
It is widely inhabited in the central and southern parts of the Americas and inhabits swamps , lakes and watery areas. The main recipe is the snail genus of snails and occasionally swallowing sea turtles , in times of drought also prey on small mammals .
Morphological characteristicsedit
Worm
The worm is a medium-sized raptor with a length of 45 cm, a wingspan of 120 cm, a body weight of 360-520 g and a life span of 17 years. The entire male head, back, wings, chest, abdomen, flank and thigh form an integral deep slate gray, with unfolded feathers and tail feathers almost black. The upper body is covered with a little brownish-grey color. The base of the tail and the base of the tail are white. The iris is dark red, some subspecies have white eyebrows, and the yellow bright colors of the eyes are different in each period. Wax, the color of the mouth is not the same. The female's head and neck are mostly gray feathers, black on both sides of the head and neck, feathers on the abdomen, a red-covered border in the middle, a male resembling a tail, an orange iris , and a bare skin on the face. [1]
The sub-adults have a slight brown color. It does not grow into the feathers of adult birds until 3 or 4 years old. Underage Asian birds cannot distinguish their gender. It resembles an adult female with dark brown stripes on the feathers and a brownish iris. The skin and feet of the face are yellow. [1] The upper side has a curved cusp, suitable for tearing the prey to swallow; the base has a waxy or whisker-like feather; the wings are strong, the wings are round and blunt, the wings are winged and soaring, and the fan-wing rhythm is more Slow; most of the ankles are relatively long, about the length of the ankle. The female is significantly larger than the male. [1]
Habitat environmentedit
The areas frequented by the worms are mainly swamps, lakes and areas with waters . Their main source of food is the snail's snail , and the habitat of these foods can be characterized as a region with standing fresh water. The place where the worms inhabit is generally small shrubs and trees. The nest site is rarely more than 1 meter high from the ground. The holly , willow and guava are the most common, and the most common is the black eucalyptus . In Florida , you also choose to visit the area near the reeds and pupa. [1]
Living habitedit
The worm is a bird that colonizes and nomads in the marshes. During the drought, leave your nest to find a suitable aquatic product area for your lifestyle and habitat. Sometimes it takes a considerable distance to travel in habitats and foraging. This raptor is very active during the breeding season, with a number of birds performing aerial acrobatics during this period. The male will briefly soar and hover in the air, slowly flapping his wings. After that, female partners will be invited to build the nest and the food provided.
The recipes and menus of the worms are almost entirely the snails of the genus Snail , occasionally consuming sea turtles , and occasionally eating small mammals during dry periods. [1]

Breeding methodedit
Because the worms are nomadic birds, their partners form alliances during reproduction , but the relationship between husband and wife is not consolidated. In Florida, the spawning period lasts for 5 months, so three or four nests are often built. If the relationship is broken and the eggs are not hatched, a new partner must be sought. Therefore, they maintain the same partnership with other similar types to facilitate active participation in brooding and rearing, but if two nests are hatched during the same breeding season, 75% of the nests are weaker and the sick chicks are abandoned by their parents. The territorial consciousness of the worms is very strong. During the spawning period, they fight for defending the nest site and the surrounding small areas. The nest site is generally selected in the food-rich waters, and the swampy trees overlook the marsh vegetation. Although the nest is quite large, the structure is loose and fragile, and it is often destroyed and caused losses. The nest is generally selected 80 days before the start of the rainy season, and the spawning season is from February to June. These birds will control the hatching period according to the season. In the right humidity and temperature conditions. Although the worm often returns to the old nest in the same place, almost every year, almost always try to build a new nest. The time to build a nest takes between 4 and 18 days, and is mainly male, supplemented by females. [1]
The worm usually produces 3 eggs in one litter, one for every two days, white or brown. Parents alternately hatch for 27-28 days. The chicks remain in the nest for 23-30 days after hatching, during which time they are fed by their parents. After take-off, it is still occasionally dependent on feeding until it reaches about 11 weeks of age. The mortality rate of young raptors is relatively high. [1]
