Aim Biogeographical comparisons of interaction networks help to elucidate differences in ecological communities and ecosystem functioning at large scales. Neotropical ecosystems have higher diversity and a different composition of frugivores and fleshy‐fruited plants compared with Afrotropical systems, but a lack of intercontinental comparisons lim...

Social monogamy with genetic polygamy is a frequent mating system in birds. In Passeriformes, extra-pair paternity (EPP) was reported in 86% of the studied species, with high variation in occurrence and frequency within and between species. In the highly diverse Neotropical region, the genetic mating system is known for only 26 bird species. We pre...

Conflicts between wildlife and agriculture have increased as cultivation has expanded into previously unexploited areas. As frequent consumers of such crops, parrots (Psittaciformes) are often persecuted, despite the lack of measured economic impacts they may cause. This situation has compromised attempts to manage potential damage and endangered p...

Seed-eating birds in temperate deserts must cope with great variation in the availability of their food resources. We studied the trophic ecology of Ringed Warbling-Finches (Poospiza torquata) in semi-arid scrublands of the Monte Desert, Argentina. We assessed seasonality in the availability of seed and in the consumption of arthropods and seeds at...

Breeding birds must choose habitat at a multiple scales, from landscapes to nest sites. It is important to understand how birds make these decisions and the relationships between these choices and breeding success. Over 3 years, we studied nest-site selection of the Ringed Warbling-Finch (Poospiza torquata) in the semiarid Chaco of Argentina at the...

1. The fruit-tracking hypothesis predicts spatiotemporal links between changes in the abundance of fruit-eating birds and the abundance of their fleshy-fruit resources. 2. While the spatial scale of plant–frugivore interactions has been explored to understand mismatches between observed and expected fruit–frugivore patterns, methodological issues s...

The Pampas Meadowlark (Stumella defilippii) is considered a vulnerable species by the IUCN (World Conservation Union) due its great range retraction and decrease in abundance over the last 100 years and also because it Inhabits one of the most modified ecosystems in Argentina. Information about its nesting requirements, site fidelity and tolerance...

Abstract (en español más abajo). – The Pampas Meadowlark (Sturnella defilippii) is considered a vulnerable species by the IUCN (World Conservation Union) due its great range retraction and decrease in abundance over the last 100 years and also because it inhabits one of the most modified ecosystems in Argentina. Information about its nesting requir...
