VIP expression, VIP-Fos double-labeling, and VIP-Fos colocalization (% of VIP neurons co-expressing Fos) in the MPO correlate positively with nesting behavior in male and female finches. (A) The number of VIP neurons (per 40 µm section) in the MPO correlates positively with time spent in the nest cup by nesting subjects, both with sexes pooled and in females alone. Males are shown in blue; females in red. Black regression lines are from analyses with sexes pooled. (C-E) The number of VIP-Fos doubled-labeled neurons also correlates positively with pick-ups (B), deliveries (C) and time spent in the nest cup (D) by nesting males and females (sexes pooled). (E) VIP-Fos colocalization correlates positively with time in the nest cup for all males. Data points from nesting subjects are shown in heavy circles; data points from subjects with nest cups only are shown in lighter circles.
