Playing with the rope: a house sparrow behaviour related to its breeding activity.

The decrease throughout August in number of total interactions and individual visits to the rope per hour was not significantly correlated with the reduction of breeding activity, but when only looking at true play behaviours correlation was close to significance (Spearman’s correlations; all levels, R 2 = < 0.01, t 30 = 0.09, P = 0.925; levels 3 and 4, R 2 = 0.11, t 30 = 1.91, P = 0.065).

True play behaviours (levels 3 and 4) disappear in the last third of August, when most of individuals were finishing or had already finished their reproductive activity, and, in fact, there is a marginally significant trend correlating both events.
