“…Adult Chilean Elaenias did not defend the nest from the wasp attack. This species has a high annual adult survival (60%, Presti et al, 2018) and a slow life-history strategy (Gorosito, 2020), which is typical of southern hemisphere bird species (França et al, 2023) that prioritizes adult survival over chick survival (Martin, 2004). We observed that Chilean Elaenias attacked predators that cannot reach them, such as rodents, but did not defend their nests against raptors, which can pursue and kill birds (C. A. Gorosito & V. R. Cueto, unpublished data, 2022).…”

Social wasps (Family: Vespidae) are opportunistic and generalist feeders, which can occasionally feed on live vertebrates. The German yellowjacket (Vespula germanica) is native to Eurasia and Northern Africa, and has invaded many countries around the world, producing several environmental, economic and social impacts. Here we report the first video‐recorded evidence that this wasp species preys on chicks. Over six breeding seasons, we studied the parental care behaviour of the Chilean Elaenia (Elaenia chilensis), a long‐distance migratory bird that breeds in the Andean‐Patagonian Forest. We filmed 59 nests when chicks were 2–3 and 10–11 days old, and recorded in a nest containing two 10‐day‐old nestlings the predation of one of them by German yellowjackets. The other chick was found alive on the ground, indicating that it escaped from the wasps. Parents did not defend offspring against wasp attacks. The rarity of this observation may suggest either that this insect is not yet a significant nest predator or that it is difficult to obtain a record of predation by wasps, because birds may remove dead nestlings from the nests (i.e. nest sanitation). Although Chilean Elaenia is not threatened, 41% of bird species in the Andean‐Patagonian Forest are endemic, and this new nest predator may potentially become a threat to the conservation of any of those species, which deserves further research. Hence, to evaluate the German yellowjacket impact on bird populations, it is imperative to conduct videotaped nest monitoring in order to remove the masking effect of nest sanitation on predator identity, which will allow to determine how much this wasp contributes to nest failure in the invaded zone of the Neotropical region.

“…Blake and Loiselle (2008) estimated mean survival rates across 30 species of passerine birds in Ecuadorian lowland forest as 0.58 6 0.02 SE. The largest single review generated survival rate estimates of 0.30-0.80 for 69 species of tropical and south temperate New World landbirds (França et al 2023). Mean annual survival rate estimates for 14 species of resident Malaysian lowland forest birds were 0.41 for first-year birds and 0.77 for all others (Francis and Wells 2003).…”

Survival data on Asian and other tropical landbirds is scant and most often derived from studies of birds in forest habitats. Open-country and human-modified habitats are less well studied, even though they may support bird species of conservation concern. We estimated apparent survival probability using open population capture–recapture (Cormack-Jolly-Seber) models for 9 relatively common species of birds over a 20 year period in a managed wetland at His Majesty the King's Royally Initiated Laem Phak Bia Environmental Research and Development Project, Phetchaburi, Thailand. These included 1 kingfisher and 8 passeriforms, 3 of which are long-distance migrants. Recapture probabilities for the studied species were low (0.03–0.20) and mean annual survival probabilities for all lay within the range 0.30–0.73. The longest recorded interval between initial capture and recapture was 11 years for 2 resident species, Malaysian Pied Fantail (Rhipidura javanica) and Common Tailorbird (Orthotomus sutorius). Banding data should be used more widely to study the life-history and population parameters of a wider range of species, particularly those for which human-modified landscapes constitute a major proportion of their available habitat, and which may suffer stress from intensification of land use.
