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.

Study site
Name	Boshoek
ID	BOS
Country	Belgium
Size (ha)	>1000
Major site changes	No
Latitude	51° 08' N
Latitude	4° 31' E
Number of nest boxes (min)	155
Number of nest boxes (max)	437
Vegetation Type	Deciduous
Description of study site	Managed forest with dense mature stands of oak Quercus robur, patch TU composed of beech, larch and some oak. Main set of plots: 12 small patches of managed forest (total surface 49 hectare, plot size from 0.25 to 11.9 ha), very similar to each other, but separated by open space (grassland, fields, residential areas, roads, poplar stands without nestboxes). Local recruitment is high, due to comparatively low dispersal and high capture rates. Areas and nestboxes: see plot descriptions. In main plots number of nestboxes = 421 (4 to 96 per plot); Boxes at ca. 1.5m height in most plots, at 2-3m in KB only. 2/3 of boxes had 32mm opening, 1/3 had 26mm opening from 1994 to 2015; from 2016 all had 32mm openings. In 1994 and 1995 area TU was only partly covered. Apart from the 12 main plots several other plots had nestboxes for variable number of years and periods.

Species
Species	Great tit, blue tit, pied flycatcher, Eurasian nuthatch
Start year	1994
End year	NA
Continuous collection of data	Yes
Gap years	NA
Longest data collection	25
Parental ID's recorded	Yes
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	No
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).

Catching data
Individual data	Yes
Type of individual data	Capture method, observer, sex, age (first-second year or older), wing length, tarsus length, weight/time, moulting of alula in first years (new/old), ticks and other parasites, personalitty scores (2006-2017).
Feeding data	Yes
Type of feeding data	Prey size, prey type, prey number. See Nour et al. 1998. Oecologia 114: 522-530
Other catching data	Number of dead nestlings, number of unhatched eggs, laying interruptions
Roosting checks	Yes
