On behalf of the local committee, The Field Museum and the local host universities, I am pleased to have you with us at the Palmer House for the 131st meeting of the American Ornithologists’ Union and the 83 rd meeting of the Cooper Ornithological Society. It will be the first time that The Field Museum has hosted C.O.S. and the fourth time for A.O.U. (previously 1922, 1934, 1982). So there is a long his- tory of ties between our institution and the ornithological societies. The 1922 meetings in Chicago were attended by such legends as C. E. Hellmayr, Margaret Nice, Ludlow Griscom, Frank M. Chap- man, Arthur A. Allen, and Arthur C. Bent. These were the first AOU meetings held away from the eastern seaboard or the west coast. What would this group think of the progress that will be presented 91 years later? We have assembled a set of plenary sessions, workshops, and other events that we think will highlight well the theme of the meeting: North American Ornithology: past, present and future. These are heady times for the science of ornithology. Looking to the past, there will be the opportunity to learn about new fossil discoveries from North America that are providing new insight into avian evolution. Looking forward, there will be presentations on the burgeoning field of genomics. Of course, many of the issues being discussed have not changed tremen- dously, concerns about the effects of humans on birds continue, but the tools we have to work with now include satellite imagery and increasingly complex computer modeling to make better ecological and evolutionary assessments of where things may be going. The societies are dealing with the digital age as well. Now is a critical time to discuss and plan for the next 91 years. We hope these meetings will provide ample opportunity for stu- dents and professionals to interact and learn from each other. With an eye on the future, local committee member Nick Block worked with Midwestern ornithological groups to provide schol- arships for a group of high school birders to spend a day at these meetings. Fully half of the meeting’s presenters are students. What will these young scientists be studying about birds in 20 years? We encourage you to take in everything you can at the Palmer House, where all the con- current sessions will all be close together. There will be an Ostrich Run, a Quiz Bowl, a showing of a new documentary on birds and other events. The end of the meeting banquet will be held at The Field Museum where we will first take another group photo of those in attendance so that 91 years from now there will be a visual record of those who have assembled. Following a “Taste of Chicago” themed dinner, people will have the chance to experience some of the best bird exhibits in the world, including the Rice DNA Discovery Center, The Abbott Hall of Conservation, the spectacular Green River bird fossils in Evolving Planet and the most comprehensive display of birds in North America in the newly renovated Ronald and Christina Gidwitz Hall of Birds.

    Nesting Behavior of Reddish Hermits (Phaethornis Ruber) and Occurrence of Wasp Cells in Nests

    NESTING BEHAVIOR OF REDDISH HERMITS (PHAETHORNIS RUBER) AND OCCURRENCE OF WASP CELLS IN NESTS YOSHIKA ONIKI REDraSHHermits (Phaethornisruber) are small hummingbirdsof the forested tropical lowlands east of the Andes and south of the Orinoco (Meyer de Schauensee,1966: 161). Five birds mist-nettedat Belem (1 ø 28' S, 48ø 27' W, altitude 13 m) weighed2.0 to 2.5 g (average2.24 g). I studiedtheir nestingfrom 14 October1966 to October1967 at Belem, Brazil, in the Area de PesquisasEco16gicas do Guam•t (APEG) and MocamboForest reserves,in the Instituto de Pesquisase Experimentaqfio Agropecu•triasdo Norte (IPEAN). Names of forest types used and the Portugueseequivalents are: tidal swamp forest (vdrze'a), mature upland forest (terra-/irme) and secondgrowth (capoeira). In all casescapo.eira has been in mature upland situations. At Belem Phaethornisruber is commonall year in the lower levels of secondgrowth (capoeira) where thin branchesare plentiful. Isolated males call frequently from thin horizontal branches,never higher than 2.5-3.0 m. The male sits erect and wags his tail forward and backward as he squeaksa seriesof insectlike"pi-pi-pipipipipipi" notes, 18-20 times per minute; the first two or three notesare short and separated,the rest are run togetherrapidly. The bird sometimesstops calling for someseconds and flasheshis tongue in and out several times during the interval. I foundno singingassemblies of malehermits such as Davis (1934) describes for both the Reddishand Long-tailedHermits (Phaethornissuperciliosus). and Snow (1968) for the Little Hermit (P. longuemareus). Breeding season.--The monthly rainfall at Belem in the year of the study was 350 to 550 mm from January to May and 25 to 200 mm from June to December,with lows in October and November and highs in March and April.

Animal Behavior and Cognition, 7(2), 247-256. doi: https://doi.org/10.26451/abc.07.02.14.2020 Abstract – While black-capped chickadees (Poecile atricapillus) primarily produce fee-bee songs in spring, they produce chick-a-dee calls year-round with call production peaking in the fall. This call serves multiple functions, including food location, flock communication, and predator alarm. As seasons change, the meaning of the call may also change. For instance, flock communication could be more important in the fall than in the spring, and food type and availability change according to season. To determine if the chick-a-dee call varies acoustically across seasons in a predictable manner, we conducted an operant go/no-go discrimination task that examined black-capped chickadees’ ability to categorize calls produced in two different seasons: fall and spring. We found that birds trained to respond to vocalizations produced in either fall or spring learned to discriminate at the same rate as birds trained to respond to pseudorandomized stimuli, suggesting that none of the groups demonstrated category learning, relying instead on rote memorization.

    Project Ecology of plant-hummingbird interactions along an elevational gradient Scientific Progress Report Project leader: Catherine Graham, Swiss Federal Research Institute Principal investigator: María Alejandra Maglianesi, Universidad Estatal a Distancia Coordinator: Emanuel Brenes Rodríguez, Universidad Estatal a Distancia Study site Las Nubes Biological Reserve York University San José, Costa Rica January, 2020 1 INTRODUCTION A primary aim of community ecology is to identify the processes that govern species assemblages across environmental gradients (McGill et al. 2006), allowing us to understand why biodiversity is non-randomly distributed on Earth. Mutualistic interactions such as those between plants and their animal pollinators are the major biodiversity component from which the integrity of ecosystems depends (Valiente-Banuet et al. 2015). The interdependence of plant and pollinators can be assessed using a network approach, which is a powerful tool to analyze the complexity of ecological systems (Ings et al. 2009), especially in highly diversified tropical regions. Mountain regions provide pronounced environmental gradients across relatively small spatial scales and have proved to be a suitable model system to investigate patterns and determinants of species diversity and community structure (Körner 2000, Sanders and Rahbek 2012). Although some studies have investigated the variation in plant–pollinator interaction networks across elevational gradients (Ramos-Jiliberto et al. 2010, Benadi et al. 2013), such studies are still scarce, particularly in the tropics. In the Neotropics, hummingbirds (Trochilidae) are considered to be effective pollinators (Castellanos et al. 2003). They have been classified into two distinct groups: hermits and non-hermits, which differ mainly in their elevational distribution and their level of specialization on floral resources, i.e., the proportion of floral resources available in the community that is used by species (Stiles 1978).

    The Behavior and Ecology of Hermit Hummingbirds in the Kanaku Mountains, Guyana

    THE BEHAVIOR AND ECOLOGY OF HERMIT HUMMINGBIRDS IN THE KANAKU MOUNTAINS, GUYANA. BARBARA K. SNOW OR nearly three months, 17 January to 5 April 1970, my husband and I F camped at the foot of the Kanaku Mountains in southern Guyana. Our camp was situated just inside the forest beside Karusu Creek, a tributary of Moco Moco Creek, at approximately 80 m above sea level. The period of our visit was the end of the main dry season which in this part of Guyana lasts approximately from September or October to April or May. Although we were both mainly occupied with other observations we hoped to accumulate as much information as possible on the hermit hummingbirds of the area, particularly their feeding niches, nesting and social organization. Previously, while living in Trinidad, we had studied various aspects of the behavior and biology of the three hermit hummingbirds resident there: the breeding season (D. W. Snow and B. K. Snow, 1964)) the behavior at singing assemblies of the Little Hermit (Phaethornis Zonguemareus) (D. W. Snow, 1968)) the feeding niches (B. K. Snow and D. W. Snow, 1972)) the social organization of the Hairy Hermit (Glaucis hirsuta) (B. K. Snow, 1973) and its breeding biology (D. W. Snow and B. K. Snow, 1973)) and the be- havior and breeding of the Guys’ Hermit (Phuethornis guy) (B. K. Snow, in press). A total of six hermit hummingbirds were seen in the Karusu Creek study area. Two species, Phuethornis uugusti and Phaethornis longuemureus, were extremely scarce. P. uugusti was seen feeding once, and what was presumably the same individual was trapped shortly afterwards.

    Do Sympatric Heliconias Attract the Same Species of Hummingbird? Observations on the Pollination Ecology of Heliconia beckneri and H. tortuosa at Cloudbridge Nature Reserve Joseph Taylor University of Glasgow The Hummingbird-Heliconia Project The hummingbird family (Trochilidae), endemic to the Neotropics, is remarkable not only for its beauty but also because of its ability to hover over a flower while feeding, its wing movements a blur. These lively birds require frequent, nutritious feeding to sustain their expenditure of energy, and some plants have evolved to attract and feed them in exchange for pollination services. Prominent among such plants are most species in the genus Heliconia (Heliconiaceae), which are medium to large clone-forming herbs with banana-like leaves (Stiles, 1975). The hummingbird-Heliconia interdependence is a good example of co- evolution, and this study is concerned with one aspect of this relationship. Since several species of hummingbird and Heliconia exist at Cloudbridge, a middle-elevation nature reserve in Costa Rica, we wondered whether particular species of Heliconia had evolved an attraction for particular hummingbird species, which might reduce the chances of hybridisation and pollen loss; or whether the plants compete for a variety of hummingbirds. At Cloudbridge, on the Pacific slope of southern Costa Rica’s Talamanca mountain range, Heliconia beckneri , an endangered species (website 1) restricted to this area and thought to be of hybrid origin (Daniels and Stiles, 1979; website 2), and H. tortuosa occur together. Stiles (1979) names the Green Hermit ( Phaethornis guy ) as the primary pollinator of both species and the Violet Sabrewing ( Campylopterus hemileucurus ) as the secondary pollinator of H.
