Crows: Description, Mating, Crow Control
The Crow is believed to be the most intelligent of all birds. When trying to open nuts, it will purposely place them in the roadway so cars will crack them open. Crows are identified by their black feathers, black eyes and the caw-caw sound they make. Adult crows have a light violet gloss on their body and a greenish blue gloss on their wings.
Crows thrive mainly on corn, thus the reason scarecrows are put up in corn fields as well as other food crops and gardens. They damage corn crops by tearing open the cobs and exposing them to the weather. These birds can be seen sometimes following a plow so that they can feast on exposed earthworms. Although they cause damage to corn crops, crows are very beneficial to farmers by eating the June bugs, grasshoppers, weevils, and other insects that affect farmers’ fields. They also eat bugs, worms, road kill, mice, berries, spiders, millipedes, snails, salamanders, lizards, small mammals and fast food leftovers. Crows like to store any excess food they may find. They usually hide food in areas such as trees or in rain gutters.
Reproduction Habits of Crows
When courting, the adult crow fluffs his feathers, struts and fly in circle to attract a female crow. Once mated, the male and female crows stay together for life. Both take turns sitting on the 4-6 eggs in the nest. When building the nest, younger birds help build the nest and bring food and water to the mother to be. Building a nest usually take 1-2 weeks of gathering leaves, moss feathers, grass, twigs, and sticks. Baby crows stay in the nest up to 2 months before leaving. Adult crows can live up to ten years and are 21 inches from beak to tail when fully grown.
Roosting and Migration
are found all around the world except in
are both migratory and resident. The Northern Crow usually migrates in the
fall through January when the weather can get down to 0 degrees. Crows
have been known to travel over 1500 miles to migrate to agricultural lands.
Southern crows normally do not migrate as do their northern cousins.
can sometime be mistaken to be ravens and vice versa. Between the two, the
Crow is the smallest. Although the raven is black like the crow, it is the
largest of the two species and has a shaggy throat feature as well as a wedge shaped tail
that is most recognized when flying. When in flight, the raven's tail is
fanned out. Ravens also
soar more than crows.
More so than most other birds, Crows are also very territorial. They will come to the aid of unrelated crows in need of help or distress. Owls and hawks are their main enemies.
Crow Control - Safe, Humane and Effective
As fascinating as these intelligent birds can be to watch in action, there are times when they become a pest, as well as times when they are beneficial. Crows are helpful when it comes to getting rid of road-kill on our roads, highways and Interstate system. Animal carcasses are picked at until light enough to be carried out of the path of passing automobiles. But these birds are usually considered a pest when they come into contact with humans and structures not built as bird houses. Damage from crows can be tremendous in areas of agriculture as well as health hazards and other damage around people, buildings, airports and many other such areas.
We must always keep in mind that
crows are much more intelligent than the average pest bird - pigeons, sparrows,
geese and others. With intelligence comes the ability to adapt and change
Proof and Bird
Strips are great bird roost inhibitors.
If only one type of deterrent is used, birds will quickly adapt, calling
your bluff. Audible units are most effective against most pest birds
(including crows) but even they need additional help to bring about effective
control of crows. Always combine at least two or
more types of bird repellers to get control of the situation. For
on-going control or prevention, at least one and sometimes two types of repeller
should be kept in place. Each location and situation demands its own
attention to detail.
Another advantage of using electrical audible devices is their flexibility. Different predator sounds and different bird distress calls can be combined for a sound that frightens or confuses birds. These sounds can be re-programmed at any point when you believe that the birds might be getting used to the current sound setup.
