“…Although not explicitly tested in our study, use of auditory and visual signals for territory advertisement by hummingbirds could influence the relationship between location of core areas and canopy height (Ewald and Bransfield , Ornelas et al ). In addition, use of exposed perches by hummingbirds is often associated with detection of intruders, leading to a correlation between territorial movements and visibility (Rousseu et al , Lanna et al ). Further direct comparisons between the density of exposed perches and space‐use patterns in territorial hummingbirds are needed to test these relationships.…”

For many territorial hummingbirds, habitat use is influenced primarily by the interaction between resource acquisition and non-foraging behaviors such as territory advertisement and defense. Previous research has highlighted the importance of foraging-associated habitat features like resource density and distribution in determining the space-use patterns of hummingbirds. Less is known, however, about how habitat selection associated with non-foraging behaviors influences space use by territorial species. We used radio telemetry to examine patterns of territorial space use by Shining Sunbeams (Aglaeactis cupripennis) in high Andean montane forests near Manu National Park, Peru, and Bosque Comunal "El Carmen" near Chordeleg, Ecuador. We quantified within-territory habitat characteristics related to resource acquisition and non-foraging behaviors such as territory advertisement and defense. We found that Shining Sunbeams showed high use of core areas in territories where foraging effort was relatively low. We found no relationship, however, between the position of core areas and habitat characteristics associated with territory defense, predator avoidance, or other non-foraging behaviors. We also found no relationship between use of non-core areas and habitat use based on resource acquisition. Thus, patterns of territorial space use by Shining Sunbeams may be characterized by core areas not determined by foraging behavior. Further studies examining territorial behaviors and the influence of intrusion pressure will help identify the underlying determinants of territory space use by this and other species of Andean hummingbirds.

“…Natural perches are commonly utilized by hummingbirds for short rests while moving across the land, as well as for territorial defense. Recent research has suggested that some hummingbird species prefer perches less than 2 m in height and less than 4 mm in diameter (Lanna et al, 2016). The low richness and incidence of this family in the present review might be associated with the utilization of artificial perches outside the preferences of this group.…”

AbstractArtificial perches are widely used in ecological restoration projects; however, the results of these works are yet to be summarized in a review. The goal of the present study was to describe the taxonomic structure of birds that utilized artificial perches, as well as determine the species of birds that most frequently utilized the perches in restoration areas of the Cerrado and Atlantic Forest biomes. We used secondary data obtained from a systematic review of literature available on digital sources. A total of 17 studies were obtained for the two biomes, 15 of which were analyzed. From these studies, 126 bird species were recorded, averaging 19.26 ± 8.30 SD species per study. Five species were categorized as frequent users of artificial perches (Pitangus sulphuratus, Tyrannus melancholicus, Mimus saturninus, Columbina talpacoti, and Tyrannus savana). These birds are predominantly generalist species, which disperse seed under the perches and this feeding habit of this group has implications for the restoration process. The large number of species that utilize artificial perches highlights the importance of these structures in supporting bird diversity, in addition to the promotion of bird ecosystem services.Keywords: nucleation, birdlife, ecosystem services, agroecosystems. ResumoPoleiros artificiais são amplamente utilizados em programas de restauração ecológica, mas ainda não há uma síntese sobre os principais resultados obtidos. Desse modo, objetivou-se descrever a estrutura taxonômica e diagnosticar quais espécies da avifauna usam mais frequentemente poleiros artificiais destinados à restauração nos biomas Cerrado e Mata Atlântica. Este trabalho utilizou dados secundários obtidos por meio de uma revisão sistemática em levantamentos previamente publicados em meio eletrônico. Foi obtido um total de 17 estudos para os dois biomas, sendo que 15 foram analisados, obtendo-se o registro de 126 espécies, com média de 18,50 ± 8,04 aves por estudo. Cinco espécies foram categorizadas como frequentes em poleiros artificiais (Pitangus sulphuratus, Tyrannus melancholicus, Mimus saturninus, Columbina talpacoti e Tyrannus savana). Essas espécies são generalistas, as quais dispersam sementes sob os poleiros, e esse hábito alimentar tem implicações no processo de restauração ecológica. O elevado número de espécies capazes de ocorrer em poleiros ressalta a importância dessas estruturas na manutenção da diversidade de aves, auxiliando na prestação de serviços ecossistêmicos.Palavras-chave: nucleação, avifauna, serviços ecossistêmicos, agroecossistemas.

Interspecific competition can strongly influence community structure and shape niche breadth and overlap. One of the main factors that determine the hummingbird community structure is competition for food. Hummingbirds functional attributes, such as beak length and body mass, influence nectar acquisition in the flowers, shaping foraging niches according to hummingbird dominance and foraging strategy. This study evaluates how the hummingbirds' functional and behavioral attributes are related to plants assemblage in rocky outcrops' habitats. We tested the following hypothesis: H1) Functional traits (beak length and body mass) are related to the richness and frequency of pollen grain morphotypes carried by hummingbirds; H2) Dominant and territorial hummingbirds carry a lower richness and frequency of pollen types when compared to subordinate hummingbirds, and H3) Hummingbird species carry different types of pollen grains. We conducted the study between September 2018 and March 2019 in a Campo Rupestre (rocky outcrops) in Southeastern Brazil. Hummingbirds were captured with a trap built based on trapdoors. We recorded their beak size and body masses, marked with commercial bird rings and ink on parts of the body, and then released. Behavioral responses to artificial feeders were collected regarding each visit's time and duration and the outcome of aggressive interactions. The pollen adhered to the body parts was collected and identified in the laboratory. Our results showed that neither body size nor aggressive behaviors influenced pollen richness and frequency in rocky outcrops. Beak length was the most important hummingbirds' attribute that influenced pollen richness, but not pollen frequency. Short-billed hummingbirds carried the greatest richness of pollen grains. Pollen grain richness and frequency were not related to hummingbird body mass or aggressive behavior. The hummingbird-pollen grain interaction network has shown to be generalized in the pollen grain transport. We conclude that hummingbirds' beak length is the central morphological variable to measure pollen grain transport. It has direct implications for the pollination of different plant species.
