Using Digital Photographs to Evaluate the Effectiveness of Plover Egg Crypsis

  title={Using Digital Photographs to Evaluate the Effectiveness of Plover Egg Crypsis},
  author={Linh Phuong Nguyen and Erica Nol and Kenneth F. Abraham},
Abstract The focus of digital photography has moved from documentation to quantitative analysis. To illustrate the potential application of this diagnostic tool to quantify color and shape, we photographed both artificial and natural semipalmated plover (Charadrius semipalmatus) nests to determine what benefits, if any, were derived from egg crypsis (i.e., eggshell color and egg marking shape). This simple and cost-effective method provides precise and repeatable quantification of color and… 

Pros and cons of different methods of measuring egg coloration - photocolorimetry vs. spectrometry

It was found that two measures of egg color intensity - saturation and BGC - were significantly correlated, however classification of blue-green egg colorintensity based on saturation values obtained from a digital photography taken in a darkroom reflected egg colors more accurately, at least for human observer, than classification based on BGC values measured by spectrophotometer.

A trade‐off between overheating and camouflage on shorebird eggshell colouration

The results show that the benefits of increasing pigmentation of eggshell backgrounds and spottiness for a better camouflage are counteracted by the increased risks of overheating when eggs remain exposed to direct solar radiation.

Eggshell Conspicuousness is Related to Paternal Brood Patch Vascularisation in the American Thrashers

It is shown that the degree of male brood patch vascularisation is directly related to relative paternal incubation effort in more than 300 North American breeding birds, which suggests that American thrasher species that possess both conspicuous eggs and brood patches, have most likely evolved to keep these conspicuous nest contents concealed, thereby reducing risk of visual detection.

Camouflage and Clutch Survival in Plovers and Terns

It is concluded that measures of egg camouflage are poor predictors of clutch survival in this population of Snowy Plovers and Least Terns breeding in mixed aggregations at Bahía de Ceuta, Sinaloa, Mexico.

Quail eggs in artificial nests change their coloration when exposed to ambient conditions: implication for studies on nest predation

The results of field studies of nest predation using quail eggs might be questioned in those cases in which the camouflage has been altered due to the rapid changes in coloration, as this can affect the resulting predation rates.

Egg crypsis in a ground‐nesting shorebird influences nest survival

Nest survival decreased as the difference between the color of the eggs and substrate increased and increased with increasing variability in substrate color, although after model-averaging these effects were not well-supported.

Dual function of egg-covering in the Kentish plover Charadrius alexandrinus

Many bird species take recesses during incubation, and while the nests are unattended, the eggs may both be vulnerable to predation and reach suboptimal temperatures for embryo development. Perhaps

Imperfectly Camouflaged Avian Eggs: Artefact or Adaptation?

This work presents and evaluates five explanations which are not mutually exclusive and which may explain why eggs appear imperfectly camouflaged at the genus or species level.

Directional selection and repeatability in nest-site preferences of Semipalmated Plovers (Charadrius semipalmatus)

Using marked individuals, directional selection and repeatability of nest-site characteristics of Semipalmated Plovers on Akimiski Island, Nunavut, Canada, 2002–2005 was assessed, indicating long-term selection for these features.

Male plumage variation and its role in reproductive isolation between house sparrows (Passer domesticus) and Italian sparrows (P. italiae) & A new method for quantifying colours of Passer sparrows using digital imaging in the field

This investigation reveals differential selection pressures among plumage traits across the Alps hybrid zone, where selection against individuals with intermediate crown colour most likely plays a role in premating reproductive isolation in this species complex, thereby contributing to homoploid hybrid speciation.



Quantification of UV-Induced Erythema and Pigmentation Using Computer-Assisted Digital Image Evaluation

The feasibility of using digital photography for objective evaluation of UV erythema in different racial/ethnic groups and for measuring pigmentation changes caused by repeated exposures over a period of several weeks is demonstrated.

Digital imaging for colour measurement in ecological research

A new affordable method, which improves methods relying on human observers, to quantify patterns and colour variations, and demonstrates that the digital system provides a finer discrimination than human observers for scoring the plumage of partridges belonging to two different subspecies.

Standardizing digital photography: it's not all in the eye of the beholder.

Different digital cameras frequently used in plastic surgery practices were evaluated, using a subject photographed with each camera in the identical lighting conditions, to determine inherent differences in quality, color, and contrast of the resultant photographs.

A quantitative evaluation of pigmented skin lesions using the L*a*b* color coordinates.

This study has developed a software program using the L*a*b* color coordinate system to quantify the effect of treatment and has successfully demonstrated its clinical usefulness.

Using digital photographs and object-based image analysis to estimate percent ground cover in vegetation plots

Ground vegetation influences habitat selection and provides critical resources for survival and reproduction of animals. Researchers often employ visual methods to estimate ground cover, but these

Image Analysis Compared with Other Methods for Measuring Ground Cover

ABSTRACT Ground cover is a key indicator of rangeland health but conventional methods for measuring ground cover are labor intensive. Analysis of digital images has the potential to reduce

Egg crypsis and clutch survival in three species of blackbirds (Icteridae)

Red-winged blackbird clutches are not concealed by overhanging vegetation, and high pattern disparity may enable them to blend into a large-scale heterogeneous background, and that of Brewer's and yellow-headed blackbirds.

Avian colour vision and avian video playback experiments

The problems of faithful colour rendition are particularly severe with video, and the major benefits that the technology brings will only be realised under a limited range of circumstances, with careful validation experiments.

Limits to the salience of ultraviolet: lessons from colour vision in bees and birds.

The relative importance of ultraviolet vis à vis other primary colours in trichromatic or tetrachromatic colour spaces is discussed, and it is concluded that ultraviolet is, in most cases, no more important that blue, green or red reflections.

Within-clutch differences in egg markings did not result in differential predation rates of first and second eggs, but increases nest complexity and hence the crypticity of the clutch, and eggs of “leapfrogging” birds had the highest survival and hatching rates in the study area.
