    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

In February, March and April starlings fed in a flock on the fields near nestboxes. At night they roosted together in thousands in the reeds of a pool, 5 km from the nestboxes. In February or March each♂occupied a particular nestbox. Early in the morning they left the flock, and stayed and sang by the nestboxes for 10-30 min., then returned to the flock but returned soon. The♀visited the nestbox a few weeks later. The♂had then already started building the nest.

Later the♀largely completed it. The nests consisted of straw; during the breeding period they were lined with feathers.

The♂more often brought food to the young than the♀. An aphisigraph was used to record the number of feeds brought to the young. To determine the food of the young quantitatively and qualitatively a closely fitting collar of aluminium was placed round their necks for 4 h a day, so that they could not swallow the food. This food was removed from the oesophagus with forceps or from the nest if the young had already rejected it. The food consisted almost entirely of animals. Among 17.933 deliveries there were at least 313 species, among which 267 insect species. Earthworms were only found in minute quantities. Carnivorous arthropods formed 30 % of the food. Although plots with many Tipula larvae were more often visited by the starlings than those with fewer larvae, a colony of starlings had little influence on the population of Tipula paludosa.
