Sarcoptes scabiei or the itch mite is a parasitic mite that burrows into skin and causes scabies. Humans are not the only mammals that can become infected. Other mammals, such as wild and domesticated dogs and cats as well as ungulates, wild boars, bovids, wombats, koalas, and great apes are affected.
A number of insects, ticks, and mites attack poultry either by sucking blood or by feeding on the skin, feathers, or scales on the skin. Mites and lice are the most destructive external parasites of

The digital tendon locking mechanism of the avian foot (Aves) - Zoomorphology
Representatives of all avian orders were studied in order to establish that the tendon-locking mechanism (TLM), consisting of local specialization of the flexor tendons and the adjacent portion of the flexor tendon sheath, is by no means rare, but rather, constitutes the prevalent condition in a large majority of the avian species sampled. The areas of tubercles on the tendons and the adjacent sheath plications intermesh with one another thereby forming a true tendon-locking mechanism that maintains the distal and other interphalangeal joints of the digits in the flexed position. The TLM seems to function not only in perching, but in a wide variety of other activities of the avian foot including swimming, wading, prey-grasping, clinging, hanging, and tree climbing. The basic structural components of the mechanism are remarkably similar in the divergent avian groups adapted for these activities. Ultrastructural detail of the TLM was studied by means of scanning and transmission electron microscopy. Interdigital variation in distribution of the TLM in all of the digits of individuals were made as were comparisons of the interspecific distribution of the TLM. An analysis of the biomechanics involved in engaging the elements of the TLM and how they produce locking of the flexed joints of the digits includes a consideration of the roles of the podothecal pads, ungual flexor processes, and the elastic flexor and extensor ligaments of the toes. The components of the TLM are differentiated in early fetal development establishing that the TLM components are not acquired adventitiously in response to such factors as posthatching mechanical stresses.

What can I use for chicken perch? A chicken roost is a place where birds regularly gather to rest or sleep. The most common material used is wood. Generally a 2×4 inch piece of wood laid wide side up is perfect. Your roosts will need to be strong and stable. Another common problems with roosts … What can I use for chicken perch? Read More »
The Passive Perching Mechanism in Passeriformes Birds
Passeriformes, or perching birds and songbirds, are an order of birds that includes crows, jays, starlings, wrens, cardinals, finches and many other species. It has been suggested that these birds are able to passively perch due to a tendon locking mechanism. This allows them to rest for hours in trees without falling. When the bird's foot is placed on a perch, the weight of the bird causes the tendons to pull, thus closing the toes around the perch. However, there is currently much debate about whether the mechanism is entirely passive. Recent studies argue that the mechanism must be coupled with the active contraction of muscles. This study seeks to determine whether or not the perching mechanism in Passeriformes is passive through the analysis of morphological parameters of window-strike birds. Specifically, we looked at the angular changes of the toes as well as the distance between opposing toes, both when the foot is flexed and extended. Preliminary analysis of our results indicate decrease in many of the measured angles and distances as the foot changes from the extended to flexed position. Since this data was collected on dead birds, this suggests that the perching mechanism is in fact passive.

Hey, guys.
I have a five month old chicken that isn’t walking. He was fine Saturday and then all of a sudden, he was walking on his hawks and then not at all. His feet are curling and he can’t control his legs below the hawk. He can sit up on them but he’s very shaky when he does. We’ve been to...
