A emergency fire escape window exit means to be mounted to a wall of a building below a window, or attached in combination with a window or a door. A platform is pivotally mounted to the door, window or wall. A ladder is connected to the platform. When the platform is folded up, it provides an enclosure for the folded ladder. When the enclosure is opened, the platform falls pivotally to a horizontal position. The platform has a trap door in it, operating on hinges that also allow it to pivot… 
Lekking in fallow deer ( Dama dama ): a long walk to territoriality
TLDR
Results of a long-term study performed in the lekking fallow deer population of San Rossore, Italy, where data were collected through radio-tracking and direct observations showed that the actual position of the leK is handy with regards to female travel costs and predation risk avoidance, in accordance to the female preference and predator avoidance hypotheses.
Queuing for territory positions in the lekking black grouse (Tetrao tetrix)
TLDR
A stochastic queuing model describing territory succession toward the lek center is presented and a central territory indicates an older than average male, as well as a male with a history of high fighting rates, consistent with the hypotheses that territory position is an honest signal of male quality and that the long-term fighting effort and survival required to acquire acentral territory may increase the reliability of die signal over that of short-term display effort.
Leks in ground-displaying birds: hotspots or safe places?
TLDR
It is suggested that both models of lek-site selection are important, at least for species displaying in open habitats, and that lek centers are extremely fixed within and between consecutive breeding seasons.
Site-specific asymmetries in male copulatory success in a fallow deer lek
TLDR
In a fallow deer, Cervus dama, lek in central Italy, most copulations occurred in a few male territories on one side of the lek, and males should compete for ownership of territories preferred by females.
Wolf pack spacing: Howling as a territory-independent spacing mechanism in a territorial population
TLDR
It is indicated that howling serves as a territory-independent spacing mechanism, that will result in the use of exclusive territories when coupled with strong, year-round site attachment, but with floating, exclusive, buffer-areas about migratory packs.
The Center-Edge Effect - the Result of a War of Attrition between Territorial Contestants?
Resident birds often respond more intensely to simulated intrusions at the center than at the edge of their territories [the center-edge (CE) effect; Falls 1982]. Very few hypotheses have been
Habitat Differences and Variability in the Lek Mating System of Black Grouse
Spatially fixed territoriality has been regarded to be a general feature in lek mating systems. In the absence of territories, however, the nature of leks may change remarkably. We compared leks of
Lek organization and mating strategies in the bullfrog

TLDR
Three potential mating systems that might result from the combination of intense sexual selection plus female choice of mate are discussed: harems; polygyny based on differential territory quality; and leks.
Home Range Defense in the Red Fox, Vulpes vulpes L.
This paper describes the home range defense behavior observed when nonresident male red foxes were introduced into established home ranges of resident male-female pairs. In 12 observation periods,
Drawn into the vortex: The facing-past encounter and combat in lekking male greater sage-grouse (Centrocercus urophasianus)
Lekking male greater sage-grouse (Centrocercus urophasianus) compete with neighbours not only by strutting to attract females but also by directly challenging other males. These challenges include

Display and mating behaviour of the Black Grouse Lyrurus tetrix (L.)
TLDR
It appears that for a considerable period of spring display and the entire autumn display cocks are not sufficiently advanced to show prenuptial display and copulation.

Aggression and Population Regulation in Red Grouse
TLDR
Recent work on red grouse on a moor at about 300 m altitude in Scotland indicates that the spring breeding stock is largely determined the previous autumn, and the size of the breeding stock was annually determined through the birds' competition for territories.
Territories, Multiple Nest Building, and Polygyny in the Long-Billed Marsh Wren
THE problem of natural selection for polygyny in a bird species with a 1: 1 sex ratio has received considerable attention in earlier papers (Verner, 1963, 1964; Verner and Willson, 1966). Briefly it
Measurement of territory and home range size in birds
TLDR
The problem of measurements of territory and home range size is critically examined, and a method for standardizing measurements is proposed, illustrated by data obtained in a study of territoriality of seven southeastern species.
The Social Order in Flocks of the Common Chicken and the Pigeon
TLDR
The problems centering about the organization of flocks of birds are by no means solved despite the attention they have received; hence no general literature survey will be undertaken now.

TLDR
The size of the inner portion of the territory and the total territory size appear to be directly related to mating success in booming populations of greater prairie chickens.
The Rôle of Dominance in the Social Life of Birds
BIRD flocks are held together by mutual attractions which are often innate. Witness the flocks of Cowbirds (Molothrm ater) which gather from broods reared by a wide variety of foster parents. On the
Some Observations On Social Organisation and Non-Random Mating in Captive Burmese Red Junglefowl (Gallus Gallus Spadiceus)
TLDR
Non-random mating was observed in captive Burmese Red Junglefowl in three experimental situations and it was found that non-random female crouching occurred, the second ranking cock eliciting significantly more sexual crouches than any other male.
EARLY MORTALITY AND THE REGULATION OF NUMBERS IN BLUE GROUSE
TLDR
Variations in early mortality between years appeared to be a result of undetermined parental influences which acted before laying, and this mortality did not vary between different habitat types or areas with different breeding densities.
