説明
The dataset concerns 690 clutches with collected bird eggs and approximately 4500 found but not collected clutches, mostly in The Netherlands. Much information was available about each clutch from the collector Bernard van Dooren. This included: locality, number of eggs, reference date, status of breeding (lightly bred, severely bred), number of young on reference date, number of young eventually ringed, ring numbers, nest height, habitat and other ecological data. The egg collection is preserved in Naturalis, Leiden as well as the eight notebooks with detailed observations on the clutches by Bernard van Dooren.

| 研究の意図、目的、背景など（デザイン） | Diaries were analyzed and all relevant data about the collected and found clutches were retrieved and entered in an excel sheet. Especially data on location, bird species and collectors were collated, as well data on the clutches (eggs, young, failures etc) and the habitat in which the clutches were found. |

収集方法
Methods and skills of Bernard van Dooren are described in: Van Dooren J. & J.F.J.Jansen 2018. Eierzoeker in de Brabantse Kempen: Bernardus van Dooren (1908-1988), Limosa 91.1: 38 – 43.
| Study Extent | Most clutches are collected in the De Kempen by collector Bernard van Dooren in the 1930s-1970s. |
|---|---|
| Quality Control | Quality control was obtained including Jan van Dooren -- son of Bernardus van Dooren -- in the team. He accompanied his father often in the field while collecting clutches. Questions that arose during the digitization process of the diaries, such as geographic locations, habitat, and other issues, were checked with him. |
Method step description:
- Analyzing the diaries on the diversity and consistency of quantitative and qualitative information
- Structuring the dataset according this information
- Entering the data from the diaries, evaluating the intermediate results and adjusting the structure of the dataset where necessary.
- After completing entering, checking thoroughly all data per species successively.
- Adding information on taxonomy (based on the Dutch Species Register) and geographic information by a) transforming Dutch grid coordinates into WGS84 coordinates and their uncertainty as well by b) georeferencing textual locality descriptions.
- Writing a R-script to transform the data from Excel into DarwinCore, producing a occurrence file and measurementOrFact file
- Publishing dataset and adding detailed metadata
- Publishing original spreadsheet with more details on Zenodo.

追加のメタデータ
In the dataset there are several fields that use codes are definitions that might be not immediately clear.
For eventDate the reference date ("Referentie-datum") is used. This is the when the maximum number of eggs is found, which in most case will be the date when a clutch was found.
Record number is the number used by Bernardus van Dooren for each clutch (these numbers were not fully unique or consistent, there a new occurrenceID has been created)
The term "eimaten" (egg measurements) means how many eggs are measured (length * width) (data on eggs are at Zenodo)
For the following terms the different enumerations are used (when value =
| 目的 | Digitizing notebooks of Bernardus van Dooren with detailed information on found and collected clutches in the 1930s up to the 1970s. These notes have a high historical value and are a rich source of data on the breeding biology and breeding distribution of birds in the Kempen area, province of Noord-Brabant, The Netherlands at that time. The full dataset can be found at Zenodo , NLBIF community. |
