Incubation behaviour in a double-nesting alpine bird Alectoris graeca saxatilis: Similar nest attendance by males and females

In birds with double-nesting and uniparental incubation, such as the rock partridge (Alectoris graeca saxatilis), the male incubates one clutch, while the female incubates the other. A previous study found no significant difference in hatching and predation rates on Alpine rock partridge nests incubated by each sex. We therefore hypothesized that the incubation rhythms of both sexes would be similar. To test this, we monitored the incubation patterns of 40 nests incubated by females and 41 nests incubated by males in the French Alps between 2011 and 2020. Temperature loggers were installed within and outside the nests to record internal and ambient temperatures at 3-minute intervals. Incubation recess timing and duration were inferred from the analysis of temperature curves. We employed statistical modelling to assess the effects of the incubating bird’s sex, minimum ambient temperature, incubation day, clutch size and recess rank on various incubation parameters.

## Description of the data and file structure

#### File: recess-data_JAB.csv

**Description:** this file includes the data used for analysis of incubation rhythms of rock partridges. It consists of recesses as rows and identifiers along with variables as columns.

**Variables**

* oiseau: name of the incubating bird
* rang: rank of the recess within the day
* Duree_sortie: duration of the recess, in minutes
* date: number of days, counted from May 31st
* debut: recess start time from sunrise, in minutes
* Tmax_in: nest temperature, in °C, at recess initiation
* Tmin_in: nest temperature, in °C,  at return time on the nest
* annee: monitoring year of the incubating bird
* oiseau_an_date: name of the bird_year_date
* oiseau_an: name of the bird incubating a nest_one year (used as nest identifier)
