Data from: High nest failure in a zebra finch population and persistent predation of a nest by a monitor lizard

Predation is well known to have substantial effects on behaviour and fitness in many animals. In songbirds, nest predation is rarely observed directly, so that research focusses primarily on the consequences of predation and less on the behaviour of the predator. Here, we report predation data in a zebra finch (Taeniopygia catanosis) nest box population, highlighting a 22-min-long sequence, captured on video, of a sand goanna (Varanus gouldii) predating a zebra finch nest in the wild. This monitor lizard appeared to be extremely persistent with climbing and jumping up to the next box nine times, including three successive unsuccessful attempts that lead to a change in approach strategy. It removed all six nestlings from the nest box during those repeated approaches and consumed them. In combination with overall high predation rates in the study population we document here, the findings highlight the role that a single predator species can have on nest success and, thus potentially also breeding decisions and social organisation of the prey population. Specifically so in a species like the zebra finch which synchronises reproductive attempts through the use of social information acquired through nest inspections and which uses social hotspots where they could gather information on changes in local social composition due to the individualised signals they use.

Fig. 8 in Systematics of limbless scincid lizards from northern Madagascar: morphology, phylogenetic relationships and implications for classification (Squamata: Scincidae)

Fig. 8 Partitioned Bayesian tree based on 3693 bp of mitochondrial and nuclear DNA gene sequences (modified after Crottini et al. 2009). The clade shown is clade A of Crottini et al. (2009) which in the analyses is sister to a clade containing the genera Amphiglossus, Voeltzkowia and Pygomeles (not shown). Eumeces, Tiliqua, and Cordylus were used as outgroups (not shown). Bayesian posterior probabilities indicated by asterisks above branches: (*)= 0.90–0.94;
