An investigation into the detection of latent marks on the feathers and eggs of birds of prey [PDF]
, 2014 There are numerous enhancement techniques (physical and chemical) which have been developed for the successful visualisation of latent fingermarks. Nonetheless, problems arise when latent fingermarks require enhancement on difficult surfaces such as ...

Using field photography to study avian moult [PDF]
, 2017 Methods to obtain moult data from wild birds have not changed much over the last century and most studies still depend on checking museum specimens or capturing birds.

Water bathing alters threat perception in starlings. [PDF]
, 2012 The majority of bird taxa perform water bathing, but little is known about the adaptive value of this behaviour. If bathing is important for feather maintenance then birds that have not bathed should have poorer feather condition, compromised escape ...

Water bathing alters the speed-accuracy trade-off of escape flights in European starlings [PDF]
, 2009 Birds of most species regularly bathe in water, but the function of this behaviour is unknown. We tested the hypothesis that water bathing is important in feather maintenance, and hence should enhance flight performance. We manipulated European starlings'

A new female-like morph of juvenile male Levant Sparrowhawk (Accipiter brevipes) – Sexual mimicry to avoid intra-specific predation? [PDF]
, 2015 In migrant Levant Sparrowhawk (Accipiter brevipes) at Eilat, Israel, we noted that juvenile males had two different morphs – the one described to date in literature; and a second, previously undescribed morph, with femalelike barring on the ...

Intrafeather and Intraindividual Variation in the Stable-Hydrogen Isotope (δD) Content of Raptor Feathers [PDF]
, 2008 Stable-hydrogen isotope ratios (deuterium:protium; δD) in feathers enable researchers to evaluate patterns of avian movement and to estimate the source areas of migratory birds.

Moult of Flight Feathers in Darters (Anhingidae) [PDF]
Ardea, 2014 There is little information on flight feather moult in darters (Anhingidae). I used a combination of direct observations and photographs to confirm that the normal pattern of moult is to replace all remiges synchronously, but not all rectrices. I surmise that at least some rectrices are retained year-round because they are important for controlling ...

A Grammar for Reproducible and Painless Extract-Transform-Load Operations on Medium Data [PDF]
, 2018 Many interesting data sets available on the Internet are of a medium size---too big to fit into a personal computer's memory, but not so large that they won't fit comfortably on its hard disk.
