On a good migration night in eastern North America, If a monitoring protocol is consistently maintained, an array thousands of call notes may be recorded from a single ground-based, of microphone stations can provide information on how the audio-recording station, and an array of recording stations across a species composition and number of vocal migrants vary across region may serve as a “recording net” to monitor a broad front of time and space. Such data have application for monitoring migration. Data from pilot studies in Florida, Texas, New York, and avian populations and identifying their migration routes.

Grey Crowned Cranes
grey crowned cranes www.olpejetaconservancy.org GREY CROWNED CRANES are one of 15 species of crane. Their name comes from the impressive spray of stiff golden feathers that form a crown around their heads. Crowned cranes inhabit a range of wetlands and prefer short to medium height open grasslands for foraging. THREATS TO CROWNED CRANES The grey crowned crane is categorised as Endangered in the IUCN Red List. Populations have decreased significantly, estimated at around 80% since 1985. The main threats to cranes are habitat loss, illegal trade, and poisoning. They are considered status symbols among the wealthy. Birds are captured and eggs removed and illegally sold in large numbers. As human settlements expand, cranes are closer to farmland which they forage millet and potatoes. Large numbers are killed each year in Kenya as retaliation or to prevent crop damage. CROWNED CRANES AT OL PEJETA Ol Pejeta sits in Laikipia County which has the 5th largest crowned crane population in Kenya. In 2019, nearly 160 crown cranes were counted at the conservancy. Unfortunately, the population has been observed to be OL PEJETA on a decline. 160 POPULATION The cranes utilise marshy areas across the conservancy. Flocks of 10- 30 individuals are often observed on neighbouring wheat farms. They migrate into Ol Pejeta in search of food and are seen in large numbers during the rainy season. DID YOU KNOW? CROWNED CRANES TRACKS Crowned cranes mate for life. They dance together and preen each others necks to help strengthen their bond. www.olpejetaconservancy.org [email protected] . -

Oromia is the largest National Regional State of Ethiopia. Here we present the first comprehensive checklist of its birds. A total of 804 bird species has been recorded, 601 of them confirmed (443) or assumed (158) to be breeding birds. At least 561 are all-year residents (and 31 more potentially so), at least 73 are Afrotropical migrants and visitors (and 44 more potentially so), and 184 are Palaearctic migrants and visitors (and eight more potentially so). Three species are endemic to Oromia, 18 to Ethiopia and 43 to the Horn of Africa. 170 Oromia bird species are biome restricted: 57 to the Afrotropical Highlands biome, 95 to the Somali-Masai biome, and 18 to the Sudan-Guinea Savanna biome. -

Chapter 8 Migration Studies
Chapter 8 Migration Studies 100 Migration Studies Overview Theme he Pacific Flyway is a route taken by migratory birds during flights between breeding grounds in the north and wintering grounds in the south. Steigerwald Lake National Wildlife Refuge plays an important role in migration by providing birds with a protected resting area during their arduous journey. Migration makes it possible for birds to benefit the most from favorable weather conditions; they breed and feed in the north during the summer and rest and feed in the warmer south during the winter. This pattern is called return migration — the most common type of migration by birds. Through a variety of activities, students will learn about the factors and hazards of bird migration on the Pacific Flyway. Background The migration of birds usually refers to their regular flights between summer and winter homes. Some birds migrate thousands of miles, while others may travel less than a hundred miles. This seasonal movement has long been a mystery to humans. Aristotle, the naturalist and philosopher of ancient Greece, noticed that cranes, pelicans, geese, swans, doves, and many other birds moved to warmer places for the winter. Like others of times past, he proposed theories that were widely accepted for hundreds of years. One of his theories was that many birds spent the winter sleeping in hollow trees, caves, or beneath the mud in marshes. 101 Through natural selection, migration evolved as an advantageous behavior. Birds migrate north to nest and breed because the competition for food and space is substantially lower there. In addition, during the summer months the food supply is considerably better in many northern climates (e.g., Arctic regions).
