Healthy prairie acts as a carbon sink. The plants, during photosynthesis, take in atmospheric carbon. Some of this carbon is deposited into the soil via the roots. Soil carbon decomposes more slowly and is thus kept out of the atmosphere for longer. At a global level, soil stores ~2,000 billion tons of carbon at any given time.

Healthy prairie regulates the supply of water. As the water is absorbed into the soil, it does not travel on the surface which eliminates erosion and prevents waterways from becoming silted. Because the water is traveling through the soil and across the roots of plants, it is slowed down and reaches the streams/creeks/rivers at a more moderate, consistent flow rate. This helps to prevent flashiness, which leads to flooding and erosion along the waterways. Major benefits to Lake Lavon as prairies are helping to prevent silting of the lake, and helping to prevent flooding.

Healthy prairie regulates water quality. Rainwater and water from surrounding impervious surfaces are absorbed into the soil. It then flows through the soil horizons, along the roots of the plants both of which act as a filter. The soil and plant roots together help to remove impurities that come from roadways, roadsides, and residential areas. This is very important as it helps to improve the quality of the water in Lake Lavon.

Red-tailed Hawk

Buteo jamaicensis

The Red-tailed Hawk is our most common buteo in Texas and North America. Their range is throughout North America except the Arctic. Most birds are permanent residents of the area they are born, but the most northern birds will migrate south in the winter. In Texas, you will see more Red-tailed Hawks in winter due to this migration. In the summer only the permanent resident birds remain.

Notes: Sometimes confused with Bald Eagles, but much smaller and has black tail and black eye-stripe whereas the eagle’s tail and head are all white when adults. When Osprey’s are flying with a fish in their talons, they always hold the head of the fish forward, this is thought to make it much more aerodynamic in flight. The only raptor that can be almost completely submerged in water, when it catches a fish, and take off again.

Turkey Vulture

Cathartes aura

The Turkey Vulture is a year-round resident in Texas and is common throughout the United States. They are carrion-feeders and can be found soaring and roosting in groups. Turkey Vultures can be distinguished from Black Vultures by shape and flight. Turkey Vultures soar with a dihedral wing shape (imagine a V-shape) and they rock back and forth. Tail is long. Black Vultures soar with wings almost flat and rarely rock back and forth. They have very stubby tails.

Species Information:

Length: 25”
Wingspan: 68”
Weight: 4 lbs

Plumage: Black on back, tail and wings. Red head and pale legs. From underneath in flight, Wing tips and trailing feathers are gray compared to rest of body. Babies are white down with black head.

Habitat: Found mainly in open areas but can be seen anywhere.

Flight: Often soaring, rocking back and forth. Has dihedral (V-shape) to wings. When roosting, will open its wings to dry them off before taking flight.

Vocalization: Has no ‘vocal chords’. Only hisses.

Food: Carrion of any kind.

Nesting: Found on the ground or in unused buildings. No nests are made, just a flat surface that may be scraped out a little. They usually lay 2 eggs that are incubated for about 38 days. Young fledge in about 11 weeks. If babies are found, leave them alone, they are supposed to be on the ground. Vultures are extremely susceptible to ‘imprinting’. If humans attempt to raise them, they will become attached to humans and can’t be released into the wild. Attempting to raise baby birds is against the law unless given state and federal permits.

Defense: Vultures will ‘throw up’ their food if they feel threatened.

Note: Turkey Vultures find food by smell. They can smell carrion over a mile away. Black Vultures will follow them because they do not have a good sense of smell.

Black Vulture

Corgyps atratus

The Black Vulture is a year-round resident in Texas and is common in the southeast United States. They are carrion-feeders and can be found soaring and roosting in groups. Black Vultures can be distinguished from Turkey Vultures by shape and flight. Black Vultures soar with wings almost flat and rarely rock back and forth. They have very stubby tails. Turkey Vultures soar with a dihedral wing shape (imagine a V-shape) and they rock back and forth. Tail is long.

Species Information

Length: 25”
Wingspan: 60”
Weight: 4 lbs

Plumage: Black on back, tail, wings and head. Legs are dark gray. From underneath in flight, wing tips are gray compared to rest of body. Babies have tan down with black head.

Habitat: Found mainly in open areas but can be seen anywhere.

Flight: Often soaring with almost flat wings. When roosting, will open wings to dry off them off before taking flight.

Vocalization: Has no ‘vocal chords’. Only hisses.

Food: Carrion of any kind.

Nesting: Found on the ground, unused buildings or ledges of cliffs. No nests are made, just a flat surface that may be scraped out a little. They usually lay 2 eggs that are incubated for about 33 days. Young fledge in about 8 weeks but depend on parents for another 3 weeks. If babies are found, leave them alone, they are supposed to be on the ground. Vultures are extremely susceptible to ‘imprinting’. If humans attempt to raise them, they will become attached to humans and can’t be released into the wild. Attempting to raise baby birds is against the law unless given state and federal permits.

Defense: Vultures will ‘throw up’ their food if they feel threatened.

Note: Black Vultures do not have a good sense of smell and will follow Turkey Vultures to find food.
