And Control

The effects of food quality and overall food intake on molt have been experimentally investigated in a number of species. However, little is known concerning the influence of periodic food availability on molt parameters, although there are some associations in the field. In this study, we experimentally manipulated food availability through food deprivation during the molt of adult and juvenile European starlings, Sturnus vulgaris. By monitoring molt scores, wingtip shape, and lengths and length asymmetries of primary feathers during molt, we demonstrated that food deprivation can influence molt. Food-deprived juvenile starlings exhibited slower feather growth rates, although the duration and rate of molt were not affected. There were no differences in wingtip shape between food-deprived and control birds at the end of molt for either adults or juveniles. We also observed erratic reshedding of previously molted primary feathers in juveniles, although this did not appear to be related to the experimental treatments. The results of this study imply that feather growth rates and shedding rates are differentially affected by food availability: growth rates may be decreased when food deprivation occurs, whereas shedding rates are relatively unaffected.

Scientific Value

The methods used to preserve bird skins in museums have a potentially crucial impact on the feasibility and use of these specimens as a source of biological knowledge, although this subject is rarely broached. Study skins of birds are usually prepared with folded wings and straight legs to facilitate storage in the collection; yet, this method can hamper the measurement and examination of certain important features such as wing-feather moult. To make consultation easier for ornithologists, alternative preparation methods such as the splitting of wings and tarsi from the rest of the animal have been proposed by curators. Our aim was to study whether or not preparing bird specimens with spread limbs makes consultation simpler. First, we used two different methods to prepare two specimens each of two common European passerine species: (1) ‘traditional’ (folded wings and straight tarsi) and (2) ‘spread’ (limbs spread on one side of the body). Then, we asked 22 experienced ornithologists to identify moult limits and take three biometric measurements (wing chord, length of the third primary feather and tarsus length) from all four specimens. Subsequently, we asked which preparation method they preferred for obtaining data. The ‘spread’ preparation was preferred for moult, third primary feather length and tarsus length, whilst the ‘traditional’ preparation was preferred for wing chord. Data obtained from the folded and spread preparations were very highly repeatable within each method but only moderately to highly repeatable between methods. One of the handicaps with the ‘spread’ preparation is the increase in storage space required, a factor that should be taken into account before it is employed. Nevertheless, this specimen preparation technique can greatly facilitate consultation and therefore improve the scientific value of ornithological collections.
