Habitat
wild rock doves nest in crevices along rocky seaside cliffs, close to agribusiness or open shrub vegetation. feral pigeons live in old grow buildings in rural areas. In cities, the skyscrapers tend to take the invest of their natural cliff surroundings .

Physical Description
The rock dove has a benighted blue-grey head, neck, and chest with glistening yellow, green, and reddish-purple opalescence along its neck and fly feathers. Females tend to show less opalescence than the males. The bill is black grey-pink. Two iniquity bands across the wings are seen in most pigeons, and one blue-grey set across the dock. Rock doves and feral pigeons can be divided into a big count of unlike phenotypes, or groups based on outbound characteristics. Some of these classifications are the blue-bar, blue checker, dark checker, bedspread, and bolshevik phenotypes .

Reproduction
Pairs may be formed at any point during the year. These pairs are formed for life. Each dame works hand in glove on most aspects of reproduction and young-rearing. The male builds the nest, and the eggs are laid shortly after the nest is finished. Both males and females incubate the eggs. Eggs hatch approximately 19 days after being laid.

Behavior
Pigeons broadly walk or run while bobbing their heads forward and back. They fly with a firm and directly path. Pigeons are most frequently seen during daylight, seeking breed at night and in during the heat of the sidereal day, according to the climate. They flock while roosting, sunning, and feed, but no fun has been observed. In the cuddle territory, both sexes are aggressive, pecking intruders on the promontory .

Food Habits
Rock doves feed in the early good morning and in the mid-afternoon on the open footing. They eat chiefly seeds. Studies of pigeons in a semi-rural part of Kansas found that their diet includes the take after : 92 % corn, 3.2 % oats, 3.7 % cherry, along with small amounts of knotweed, elm, poison ivy, and barley. In cities, feral pigeons besides eat popcorn, cake, peanuts, bread, and currants. Female rock doves need to eat a diet slightly higher in protein and calcium in holy order to have the nutritional resources to lay eggs .
Economic Importance for Humans: Positive
Eaten by humans and used for testing ground research .
Economic Importance for Humans: Negative
A large act of pigeons living in a small area can be a nuisance to farmers. Some diseases ( for example, histoplasmosis ) may be spread in pigeon droppings .
feral pigeons have been used extensively in laboratories because they are domesticated and found in abundance throughout the earth. These studies include fledge mechanisms, thermoregulation, water metamorphosis, genetics of color patterns, and darwinian evolutionary biology .

- Nearctic
-
living in the Nearctic biogeographic state, the northerly part of the New World. This includes Greenland, the Canadian Arctic islands, and all of the north american as far south as the highlands of cardinal Mexico .
- Neotropical
-
life in the southerly separate of the New World. In other words, Central and South America .
- Palearctic
-
surviving in the northerly part of the Old World. In otherwords, Europe and Asia and northern Africa .
- acoustic
- uses sound to communicate
- bilateral symmetry
- having body isotropy such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and adaxial sides, vitamin a well as front tooth and later ends. Synapomorphy of the Bilateria.
- chaparral
- Found in coastal areas between 30 and 40 degrees latitude, in areas with a Mediterranean climate. vegetation is dominated by stands of dense, barbed shrub with hard ( hard or waxen ) evergreen leaves. May be maintained by periodic ardor. In South America it includes the scrub ecotone between forest and paramo .
- chemical
- uses smells or other chemicals to communicate
- cosmopolitan
- having a cosmopolitan distribution. Found on all continents ( except possibly Antarctica ) and in all biogeographic provinces ; or in all the major oceans ( Atlantic, Indian, and Pacific .
- desert or dunes
- in deserts humble ( less than 30 cm per year ) and irregular rain results in landscapes dominated by plants and animals adapted to fruitlessness. Vegetation is typically sparse, though spectacular blooms may occur following rain. Deserts can be cold or warm and day by day temperates typically fluctuate. In dune areas vegetation is besides sparse and conditions are dry. This is because sand does not hold urine well so little is available to plants. In dunes near seas and oceans this is compounded by the influence of salt in the air and soil. Salt limits the ability of plants to take up water through their roots .
- endothermic
- animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a ( immediately extinct ) synapsid ancestor ; the fossil commemorate does not distinguish these possibilities. convergent in birds .
- forest
- forest biomes are dominated by trees, differently forest biomes can vary widely in come of haste and seasonality .
- introduced
- referring to animal species that have been transported to and established populations in regions outside of their lifelike compass, normally through human natural process .
- iteroparous
- offspring are produced in more than one group ( litters, clutches, etc. ) and across multiple seasons ( or other periods hospitable to reproduction ). Iteroparous animals must, by definition, survive over multiple seasons ( or periodic condition changes ) .
- motile
- having the capability to move from one set to another .
- native range
- the area in which the animal is naturally found, the region in which it is endemic .
- oceanic islands
- islands that are not part of continental ledge areas, they are not, and have never been, connected to a continental land batch, most typically these are volcanic islands .
- oriental
-
found in the oriental area of the earth. In other words, India and southeast Asia .
- oviparous
- replica in which eggs are released by the female ; development of offspring occurs outside the mother ‘s body .
- rainforest
- rainforests, both moderate and tropical, are dominated by trees frequently forming a close canopy with little light reaching the ground. Epiphytes and climbing plants are besides abundant. precipitation is typically not limiting, but may be slightly seasonal worker .

- sexual
- reproduction that includes combining the genetic contribution of two individuals, a male and a female
- tactile

- A grassland with break up trees or scatter clumps of trees, a type of residential district intermediate between grassland and afforest. See besides Tropical savanna and grassland biome .
- temperate grassland
-
A mundane biome found in moderate latitudes ( > 23.5° N or S latitude ). vegetation is made up by and large of grasses, the acme and species diverseness of which depend largely on the total of moisture available. Fire and grazing are significant in the long-run maintenance of grasslands.

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
