The pair formation started in February 2017 to March 2017 while breeding period lasted from early April to July 2017, indicated by breeding calls, pair formation, nest construction, egg laying and incubation.
Nesting season in the study area started from early April to May, as in earlier months breeding calls started and pair formation occurred.
They said that mating preferences, the propensity to mate with certain phenotypes, are an important part of pair formation.
The pair formation has for a long time both been studied experimentally [1] and been subject to theoretical analysis [2].
In this paper an attempt is made to understand the elementary electron-positron pair formation process in terms of a revised quantum electrodynamic theory and its application to a wave-packet model of the individual photon [3, 4, 5, 6].

Pair formation and promiscuity of cytokeratins: formation in vitro of heterotypic complexes and intermediate-sized filaments by homologous and heterologous recombinations of purified polypeptides.
Observations of pairing behavior in Hyalella suggest that females have substantial control in pair formation. Male Hyalella generally attempt to pair with any individual encountered, regardless of sex or reproductive condition (Strong, 1973; pers.
Because selection on gnathopod characters as examined in this study results from the behavioral process of pair formation, differences in patterns of selection between ecotypes reflect differences in mating behaviors.
Male urine release was necessary for stable pairing, suggesting that male urine signals may be involved in pair maintenance rather than pair formation. Females that could not receive chemical information paired faster and elicited fewer male agonistic behaviors.
Blue crab courtship can be divided into three phases: mate attraction, pair formation, and pair maintenance.
Rohwer and Anderson (1988) generally agreed with Greenwood (1980), but expanded the hypothesis to include the timing of pair formation as an important determinant of female-biased philopatry.
Probability of inbreeding in brant is greatly reduced by weak family integrity (Jones and Jones 1966), coupled with pair formation on wintering areas (Greenwood 1987, Rohwer and Anderson 1988).
