“…Habitat penetrability for access will influence patterns of access and could be used as a management tool, especially at path margins. There have been records of predation of eggs and chicks of Killdeer Charadrius vociferus (Nol & Brooks 1982) and Great Ringed Plover Charadrius hiaticulus (Pienkowski 1984a, 1984b, Liley 1999) by dogs. Birds also tend to flush more readily in response to dogs than people (Yalden & Yalden 1990, Lord et al .…”

Several successive studies of European Nightjars Caprimulgus europaeus (hereafter, Nightjar) on the Dorset heaths demonstrated negative effects of the proximity of urban development and associated disturbance from access on foot by people and dogs. Surrogate measures of human density and settlement, including the amount of developed land around each heathland patch and the number of houses, were significantly and negatively related to the density of Nightjars (using data from the 1992 national survey) on heathland patches, regardless of patch size. These findings prompted targeted field studies, the subject of this paper, which investigated the mechanisms and effects of recreational disturbance on breeding Nightjars. Fieldwork in 2002 focused on a suite of heathland sites representing a range of access from sites closed to the public to heaths heavily used for recreation, notably by dog walkers. Studies in 2003 concentrated on the heavily used heaths. Nests which failed were significantly closer to paths, tended to be closer to the main points of access to heaths, in areas with higher footpath density, notably of high levels of use, and in more sparsely vegetated locations. The proximate cause of nest failure was most frequently egg predation. Nest cameras, deployed in 2003 in an attempt to identify the predators of eggs or chicks, recorded just one instance of predation, that of an egg by a Carrion Crow Corvus corone , and two instances of the incubating bird being flushed by a dog, once from an egg and once from a chick, neither event preventing fledging. Flushing rate of Nightjars from the nest was associated with the height of vegetation around the nest and the extent of nest cover. The studies indicate that access disturbance interacts with environmental conditions for breeding birds. Birds flush more readily from eggs, which are highly visible when exposed, especially in areas with sparse nest cover, leaving them vulnerable to predation. Although Nightjar flushing rates were observed to be low in 2003, just one event leading to predation is enough to end that nesting attempt. Management measures are recommended to minimize the effects of walkers and their dogs on Nightjars.

“…The considerably higher correlation obtained for egg volume with hatchling weight than with either of the other two measurements of hatchling size in Whimbrels does not necessarily indicate that larger chicks also retained greater yolk reserves, since body weight at hatching could be more closely related to structural size than either of the other measurements taken (compare Galbraith 1988a). Mortality of wader chicks is greatest during the early stages of chick-rearing (Heppleston 1972. Pienkowski 1984, Galbraith 1988b.…”

“…Whilst an association between egg size and chick survival was found for Lapwings Vanellus vanellus on Scottish farmland (Galbraith 1988a). no significant relationship could be established in Ringed Plovers Charadrius hiaticula nesting on coastal habitats in northeast England (Pienkowski 1984).…”

Relationships between egg size, chick size at hatching, and chick survival in the Whimbrel Numenius phaeopus

The relationships between egg size, chick size at hatching a n d chick survival in Whimbrels Numenius phaeopus were studied over a three-year period in the Shetland Isles. Three measurements of 'chick size at hatching were all positively correlated with egg volume, though the relationship was strongest with hatchling body-weight. In two of the three years the proportion of chicks from a brood which survived to fledging increased significantly with the mean hatching weight of chicks in the brood. Within broods, a significant effect of hatching weight on survival was detectable only u p to 7 days after hatching. Between years the egg volumes and hatchling weights of individual female Whimbrels showed relatively little variability, indicating that these attributes could be controlled to a large extent by inheritance.

“…Shorebird chicks are dependent on the tending parent for warmth for the first 10 day of life, and progressively less so for up to a week after that (Pienkowski 1984). Piping Plover (Charadrius melodus) chicks were not observed being brooded after 14 days of age (Powell 1992), and young Semipalmated Plovers (Charadrius semipalmatus) were rarely observed being brooded after five days of age (Blanken and Nol 1998).…”

Precocial young often experience high mortality prior to achieving flight, especially in the first days after hatching. We quantified relationships between chick age, survival, behavior, and response to natural and anthropogenic danger for the threatened Western Snowy Plover (Charadrius alexandrinus nivosus) in coastal northern California, USA. Plover chicks were most likely to die in the first three days of their 28-day prefledging period, especially on sandy ocean beaches compared to coarser substrates of river habitats. Chick survival in both habitats increased across the ∼120-day chick-rearing period. Improved survival of older chicks coincided with an age-related reduction in brooding and increased distance from the tending parent, which was not related to season. Lower survival of younger chicks was correlated with a tendency to lie motionless when approached by humans; nearly all older chicks responded to human approach by running to evade danger. Chicks of all ages were more likely to lie motionless when potential avian predators flew nearby. Agedependent survival of Snowy Plover chicks paralleled a trend of increasing development, thermal independence from adults, and capability of evading predators. Abstract.
