Allowing particulates to accumulate on feathers also creates the need for cleaning which can put fragile feathers at risk for physical damage. [15] In addition, particulates can cause the relative humidity around the feather to rise. This rise in humidity and the resulting addition of moisture can accelerate the deterioration of the feather. [2]
When preening, a bird (such as this red lory) draws individual feathers through its beak, realigning and re-interlocking the barbules.. Preening is a maintenance behaviour found in birds that involves the use of the beak to position feathers, interlock feather barbules that have become separated, clean plumage, and keep ectoparasites in check.
For example, bird specimens that have been badly damaged by pests may be repaired with a mixture of synthetic fabrics and wheat starch. This mixture is used to infill areas of loss and feathers are replaced where possible with a wheat starch paste adhesive. In addition to infilling, taxidermy specimens may require structural repairs.

A relatively tall plucking post used here to dismember a toad and discard the spawn A low tree stump plucking post, used to pluck bird prey at Spier's school in Ayrshire. The elevated nature of the post allows for a safer landing with the heavy load of the prey, as well as being a good vantage point to scan for other predators, while the bird is vulnerable, involved in the relatively complex ...
Feather holes often characteristically occur on wing and tail feathers of some small-bodied species of passerines. In the case of barn swallows , it was suggested that the holes were feeding traces of avian lice , either Machaerilaemus malleus and/or Myrsidea rustica (both Phthiraptera : Amblycera ).

The bird's nesting hole requires not only the bird's making a hole but also the cactus's lining the hole - it is not ready for use as a nest until a year after its creation. [4] Many saguaros are home to multiple nests; if birds excavate adjoining hollows, a saguaro boot may be formed with more than one opening.
