Are Merlin birds rare?
From the 1950s, merlins were badly affected by organochlorine pesticides, resulting in an all-time population low by 1960 of about 550 pairs. It was only in the early 1980s that the population showed any signs of recovery. Merlins are a Red status bird with a 94 per cent increase, but they are still at threat.
How do you get rid of Merlin?
As they tend to prey on small birds, Merlins can be a nuisance to people who have bird feeders. “In the spring, they use old crow and magpie nests in big spruce trees for nesting,” Dr. James said. “The best way to keep them away is by removing the nest before or after they breed.”
Do falcons whistle?
Food can be a drawback however, as well-fed falcons hunt lazily. Hunters also use whistle tones to command the bird, but the whistle can be drowned out by bird calls or loud music. The hunter's voice is heard by the falcon for miles and some birds are trained to respond only to voice.

What is the name of the merlin?
The merlin was described and illustrated by the English naturalist Mark Catesby (as the "pigeon hawk") in his Natural history of Carolina, Florida and the Bahama Islands published in 1729–1732. Based on this description, in 1758 Carl Linnaeus included the species in the tenth edition of his Systema Naturae and introduced the present binomial name Falco columbarius with the type locality as "America". The genus name is Late Latin; falco derives from falx, falcis, a sickle, referring to the claws of the bird. The species name columbarius is Latin for "of doves" from "columba", "dove". Thirteen years after Linnaeus's description Marmaduke Tunstall recognized the Eurasian birds as a distinct taxon Falco aesalon in his Ornithologica Britannica. If two species of merlins are recognized, the Old World birds would thus bear the scientific name F. aesalon.
What is the difference between a merlin and a kestrel?
Light American males may resemble the American kestrel ( F. sparverius, not a typical kestrel), but merlin males have a grey back and tail rather than the reddish-brown of the kestrels. Light European males can be distinguished from kestrels by their mainly brown wings.
How many eggs do Merlins lay?
Three to six (usually 4 or 5) eggs are laid. The rusty brown eggs average at about 40 mm × 31.5 mm (1.57 in × 1.24 in). The incubation period is 28 to 32 days. Incubation is performed by the female to about 90%; the male instead hunts to feed the family. Hatchlings weigh about 13 g (0.46 oz). The young fledge after another 30 days or so, and are dependent on their parents for up to 4 more weeks. Sometimes first-year merlins (especially males) will serve as a "nest helper" for an adult pair. More than half—often all or almost all—eggs of a clutch survive to hatching, and at least two-thirds of the hatched young fledge. However, as noted above, in years with little supplementary food only 1 young in 3 may survive to fledging. The merlin becomes sexually mature at one year of age and usually attempts to breed right away. The oldest wild bird known as of 2009 was recorded in its 13th winter.
How do Merlins hunt?
Merlins rely on speed and agility to hunt their prey. They often hunt by flying fast and low, typically less than 1 m (3.3 ft) above the ground , using trees and large shrubs to take prey by surprise. But they actually capture most prey in the air, and will "tail-chase" startled birds. Throughout its native range, the merlin is one of the most able aerial predators of small to mid-sized birds, more versatile if anything than the larger hobbies (which prefer to attack in mid-air) and the more nimble sparrowhawks (which usually go for birds resting or sleeping in dense growth). Breeding pairs will frequently hunt cooperatively, with one bird flushing the prey toward its mate.

Why are merlins dying?
Perhaps the most frequent cause of accidental death for individuals is collision with man-made objects , particularly during attacks. This may account for almost half of all premature deaths of merlins. In the 1960s and 1970s, organochlorine pesticides were responsible for declines—particularly in Canada —due to eggshell thinning and subsequent brood failure, and compromising the immune system of adults. This has since been remedied with restrictions on the use of DDT and similar chemicals, and numbers have rebounded. Overall, merlin stocks appear globally stable; while they may decline temporarily in places, they will usually increase again eventually, suggesting that this phenomenon is due to the fluctuations of supplementary food stocks discussed above.
How much does a Merlin weigh?
