“…The trends showed by this study (richness) are consistent with those reported by Bristow and Ockenfels (2002; and Hernández et al (2006) who evaluated the habitat of Table 1. Main components that explain in three axes the proportion of the accumulated variance out of 100% of the total present variation that compose and determine the presence of the Montezuma quail.…”

Objective. To characterize the habitat of the Montezuma quail (Cyrtonyx montezumae) in Rancho Chapultepec, Durango, Mexico.Design/Methodology/Approach. From February to October 2020, fieldwork was carried out to search for Montezuma quail sites using transects and sounds. Subsequently each site-of-use was characterized; for each of them three random sites were located. Intercept lines (or Canfield), embedded frames, and nearest neighbour techniques were used. Recorded data were analysed using Principal component analysis (PCA); Frequency ofobservation (FO); Kruskal-Wallis; and Poisson regression (PR).Results. The PCA showed values for sites of use= 48, non-use= 43, and both= 36 of the present variability in vegetation-habitat variables. FO showed values per site of use = 6.25%; non-use = 2.08% and both = 1.56%; and per species in sites of use = 3.57, non- use = 3.85 and both = 3.33%. Kruskal-Wallis exhibited significant differences in richness and abundance and similarity in diversity. Poisson regression (PR) showed the effect of some vegetation-habitat variables on the Montezuma quail.Limitations /Implications of the study. The monitoring period evaluated only comprised a short space of time. It is suggested to extend the sampling time, allowing to visualize the population fluctuation regarding this variable.Findings/Conclusions: It was possible to determine that there is an association between the variables of the vegetation-habitat with the presence of C. montezumae. Vegetation type is the variable that determines the incidence of this species.

“…The fieldwork began in February and ended in October 2020; paddocks were surveyed to know where there could be quail Moctezuma (Hernández et al, 2006). For the location of the quail, quail sounds were reproduced (playback) from both sides of the transect, at 50 m taking the path as the center.…”

“…The ability to track mountain quail as they make seasonal movements in response to environmental cues is just one example of valuable information that may become readily available by employing this recapture technique. Although night-lighting methods have been described previously (Labisky 1968, Giesen et al 1982, Hernandez et al 2006, past techniques focused on species such as greater sage-grouse and Montezuma quail (Cyrtonyx montezumae) that typically roost in relatively open, flat areas (Schroeder et al 1999, Stromberg 2000. This technique provides a method to recapture individuals of species that occupy dense vegetation in steep terrain.…”

Difficulties in recapturing radiomarked birds often prevent wildlife researchers from replacing transmitters and continuing to collect data over long time periods. We developed an effective, inexpensive capture technique for radiomarked mountain quail (Oreortyx pictus). Twenty-three of 25 mountain quail in south-central Idaho, USA, in 2006 and 2007 were recaptured for transmitter replacement. This technique will provide researchers with an opportunity to recapture relatively small birds, particularly those in dense vegetation, to help conduct long-term studies. ß 2012 The Wildlife Society.

“…canes, and thus standard capture techniques were not always suitable. Consequently, females were captured generally in May or June on their nests by nets, by hand, or by retriever dogs that found nesting females and were trained to gently grab but not injure the bird; trained dogs are often used effectively to augment bird capture (Hicklin and Barrow , Hernandez et al , Robertson and Fraser ). Males were captured in July and August principally on the water by shooting a net over flocks of molting males using a net gun (Coda, Mesa, AZ, USA) discharged from a hovering helicopter (Milton et al ).…”

Sex-specific survival of adult common eiders in Nova Scotia, Canada

Common eiders (Somateria mollissima) are large sea ducks with a circumpolar distribution and have high cultural significance to sport hunters and indigenous peoples in many countries. Their gregarious habits, including colonial breeding and forming large flocks during migration and winter, make eiders susceptible to environmental stressors during breeding and non-breeding seasons. Our objective was to assess whether low adult survivorship could be contributing to suspected local population declines in Nova Scotia, Canada. We banded molting male and breeding female common eiders along the marine coastline of Nova Scotia and recaptured them in later years. We found that from 1997 to 2011, when males and females were banded, male survival (S) was high (S ¼ 0.92; 95% CI ¼ 0.87-0.95), whereas female survival was approximately 10% lower (S ¼ 0.83; 95% CI ¼ 0.78-0.87) and at a level comparable to what has been reported in other regions of the world where eider populations are thought to be in decline. Recovery rates (f) of harvested male and female eiders were indistinguishable (f ¼ 0.013; 95% CI ¼ 0.010-0.016), suggesting that lower female survival is attributable to factors other than hunting. Supplementary analyses using a longer-term data set for females only and including live recapture data indicated that female survival rates have not changed markedly during the past 40 years and that the emigration rate from colonies is low ($6%). We conclude that to successfully conserve this population, sources of non-harvest female mortality should be investigated and used to develop targeted management solutions. We speculate that one of those sources of mortality is predation on females at breeding colonies, notably from eagles and mustelids.
