Conditions of use/Licence NA
Data available via pipeline Yes
Quality check of the original data Raw data are entered in the field through an app which has checks on entries and values. Data are imported into import tables into the SAS database. Brood data are checked manually. Brood and captured data are checked by a multitude of SAS scripts to check for known types of errors and incomplete data, and for conflicts with existing data in the main database. After all checks, data are added to the main database. During analyses and data delivery, data are continuously checked and cross-checked, and inconsistensies are corrected if needed.

List of basic breeding data collected Lay date, clutch size, brood size, number fledged
Description of the protocols for breeding data collection A breeding attempt is defined as any nest in which at least one egg was laid. Attempts stopped during the nest building phase are not included in the database.
Description of the protocols for taking individual level measurements All capture data, i.e. all occasion in which a bird is handled or its location and status as recorded by electronic devices (e.g. radio-transmitter, pit-tag, …), are collected.
Experimental manipulations Yes
Description of experimental manipulations NA
Predation events recorded No
How are second clutches recorded? Broods are given 10 classifications:
  • 0: Female breeding on nest with 0 eggs
  • 1: First brood. The first nest of a known female in a given year
  • 2: Second brood. Second nest of a known female in a given year. Identity of female/parents known AND at least one chick fledged successfully in first clutch.
  • 3: Replacement clutch. Second nest of known female AND no chicks in first nest (nest abandoned before hatching).
  • 4: Replacement clutch. Second nest of known female AND chicks in first nest (nest abandoned after hatching).
  • 5: Replacement clutch. Late nest but no female/parents known from a first nest AND one or more nests (with unknown parents) known to have failed in the vicinity with a timing which could comply with the timing of the start of the current nest.
  • 6: Third brood. Third nest of a known female in a given year. Identity of female/parents known AND at least one chick fledged successfully in first and second clutch.
  • 7: Third brood. Third nest of a known female in a given year. Identity of female/parents known AND at least one chick fledged successfully in first OR second clutch.
  • 8: Second replacement clutch. Third nest of a known female in a given year. Identity of female/parents known AND no chicks fledged successfully in first NOR second clutch.
  • 9: Extra pair/Late first brood. Nest for which no first nest/parents/female is known AND no nest failures with acceptable timing could be indicated in the vicinity (thus, no replacement clutch). First egg date at least 10 days later than last documented genuine first brood (thus, no ordinary first brood).
