Abstract:
... Vaccines against Marek’s disease can protect chickens against clinical disease; however, infected chickens continue to propagate the Marek’s disease virus (MDV) in feather follicles and can shed the virus into the environment. Therefore, the present study investigated if MDV could induce an immunoregulatory microenvironment in feathers of chickens and whether vaccines can overcome the immune evasi ...

Abstract:
... The claims of an array of specimens to be considered part of the type series of Pitta gurneyi are clarified. The plate of P. gurneyi that is commonly linked to the type description in Stray Feathers was based on two specimens Hume gave to Gurney and was published considerably after the type description itself. ...

Abstract:
... Duck down, as a natural keratin material, has been widely used as a filling material. The multilevel bifurcation structure of down has been observed and characterized through scanning electron microscopy. The structure is a complex fractal structure composed of four-level self-similar structures including five units, that is, the calamus, main barb, barb, barbule, and node or prong. The differenti ...

Abstract:
... Suspended moult is a relatively common phenomenon in birds, but it has remained relatively ignored for a long time in studies dealing with moulting process. Furthermore, the new and increasing number of models used to estimate moult duration systematically omit the fact that suspended moults can occur and that they significantly alter parameter estimates. Taking suspended moults into account is cr ...

Abstract:

The Yellow-shafted (auratus group) and Red-shafted (cafer group) subspecies groups of the Northern Flicker (Colaptes auratus) differ conspicuously in the coloration of their flight feathers, but hybridize freely where their ranges overlap in w ...

Abstract:
... Double-brooding is an avian breeding strategy where birds produce at least two successful nests in a single season. Double-brooding is seen most frequently in small passerines for which the breeding season is lengthy enough that they can easily fit in multiple nesting attempts. Such a pattern of breeding is therefore less common among large birds with long incubation periods and slow offspring dev ...

Abstract:
... Despite the excitement that followed the report of infrasound sensitivity in pigeons 40 years ago, there has been limited followup, with only eleven species of birds having auditory thresholds at frequencies below 250 Hz. With such sparse data on low-frequency hearing, there is little understanding of why some birds hear very low frequencies while others do not. To begin to expand the phylogenetic ...

Abstract:
... This paper reveals the complexes of structural signs of body feathers in Charadriiformes bird species that have a taxonomical value. The complexes of structural signs are united in a system of diagnostic signs, which is used to identify bird taxa by one body feather, a part of a feather, and/or feather fragments. It is noted that the successful definition of a taxon requires the use of signs withi ...

Long tail feathers of the barn swallow Hirundo rustica are a classic example of an intersexually selected trait, but previous aerodynamic analyses indicate that the tail feather is only 10–12 mm longer than the aerodynamic optimum even in the nominate subspecies with long tails. Here, by experimentally shortening female tail length, we studied the feeding cost of long tail feathers in Japanese bar ...
