In Zeeland (Delta area) a number of (breeding) biological parameters were determined from Tern and Common Tern. The dataset is the result of determining breeding success of 25 to 50 marked nests of Tern and Common Tern in a number of colonies in the Delta area (Zeeland).

1 Mei 2009 - 1 Augustus 2011 Jaarlijks Parameters
Broedsucces: Count of eggs per nests Number of eggs per nest are counted in 30 to 40 individual enclosed nests in a representative area of the colony. Counted nests are marked and counted eggs are marked. Egg size: Count of percentage of hatched eggs Cause of loss are noted: predation, trampling, flooding. Hachlings are ringed individually within 3 days from hatching. Leggrootte: Count of % of hatched eggs that actually fledged Cause of loss is noted: predation, found death (starvation or dehydratation). Rule for success of fledging is that winglength exceeds 160 mm for Common tern and 180 mm for Sandwich tern and Black headed gull. Bijdrage door
