Figure 1. Percentage of new neuronal recruitment into the hippocampus (HC) and nidopallium caudolateral (NCL) of the turtle dove (Streptopelia turtur), as a function of the migration distances from their wintering grounds in Africa to Israel.

For the HC, Spearman’s rank correlation, P = 0.96; ρ = −0.14 (N = 11) and for NCL P = 0.07; ρ = 0.53 (N = 12).
