title: Climate effects on the breeding ecology of pied flycatchers at the north of their range

description: The file “Raw data.csv” contains all data used for the analyses of the
 article “The effects of four decades of climate change on the breeding
 ecology of an avian sentinel species across a 1500-km latitudinal gradient
 are stronger at high latitudes” (DOI: 10.1002/ece3.7459). This data was
 used to investigate the effect of climate warming on the breeding time and
 breeding success of European pied flycatchers breeding in Sweden during
 1982-2017. The data set contains 29035 nest records and each row has
 information per nest on ringing date of nestlings, developmental stage of
 nestlings and estimates of hatching date, nestling age, and breeding
 success (measured as number of ringed chicks). It also contains
 geographical coordinates per nest and distance to the coast variables as
 well as environmental data for different biweekly periods before and up to
 ringing time (average and minimum temperature, precipitation and a
 measurement of vegetation greenness). The precise definition of all the
 variables can be found in the ReadMe file. The specific information on
 data collection, processing and statistical analyses is available in the
 corresponding article.

 Details on the variable names found on “Raw data.csv”
 Note: Every row gives information on a pied flycatcher nest. More
 details in “Methods” section and Fig. 3 (for the understanding of the
 periods analysed) of the corresponding article.
 Ring.date: Ringing date of pied flycatcher nestlings<br>
 Longitude: Longitude in decimal degrees<br> Latitude: Latitude in
 decimal degrees<br> LocID: Or “location ID” is a categorical
 variable that gives information on the geographical location of the pied
 flycatcher nest boxes and it is created by the unique combinations of
 longitude and latitude coordinates of each nest boxes<br>

 Developmental stage of the chicks per nest<br> Hatch.date: Estimated
 hatching date of chicks<br> Chick.age: Estimated chick age in
 days<br> Dist.m.coast: Distance from the nest to the nearest coast
 in meters<br> Dist.band.3: Distance to the coast transformed into a
 categorical variable with three levels (level 1 = closest to the coast;
 level 2 = intermediate; level 3 = most inland level) <br>
 Dist.band.2: Distance to the coast transformed into a categorical variable
 with two levels (only used at southern latitudinal band where there were
 very few nests at distance level 3 of above variable)<br> Latband:
 Categorical variable with three levels (southern, intermediate and
 northern) Measurements of Normalized Difference
