New Data on Breeding Strategies and Reproductive Success of the Globally Threatened Turtle Dove Co-Occurring with the “Competitive” Collared Dove and the “Predatory” Maghreb Magpie in Olive Orchards

Table 1

Comparison of nest placement and dimension (n = 60 nests) parameters between dove species and magpie (mean ± SE) was tested using one-way ANOVA. (NBD: big nest diameter, NDLC: distance between nest and the lower canopy, NDCT: distance of nest to tree center, NDP: nest depth, NSD: small nest diameter, NHG: nest height upon the ground, NTH: nesting tree height).
