Set of supported (Δi<2) and best non-supported (Δi>2, between brackets) models for habitat preference (arrival date, wing length and mask size of males) and reproductive performance (nest success, brood size and nestling body condition) measures along with their respective support (AIC_c weight).

<p>Δi refers to the differences in AIC_c between the model and the best candidate model associated with the smallest AIC_c. The number of parameters (K) is reported for each model.</p><p><u>Response variables</u>: Arrival date of males = arrival dates of males in springtime, Male wing length = outermost primary wing length in males, Male mask size = size of black eye-stripes in males, Nest success = production of at least one fledgling, Brood size = number of nestlings older than 12 days, Nestling body condition = PCA-based combination of nestling tarsus length, wing length and body mass.</p><p><u>Fixed effects</u>: F/W = farmland (F) versus woodland (W) sites, Clutch sequence = first versus replacement clutches, Year = 2008, 2009 or 2010, Study area = 1 or 2, Aggregation = number of males settled within a radius of 500 metres.</p><p><u>Random effects</u>: territory site identity (for arrival date, male wing length, nest success and brood size) or nest identity (for nestling body conditions).
