Photographic records of the probable consumption of the carcass fragment (one wing) of a young Scarlet Ibis (Eudocimus ruber) by a Boat-billed Heron (Cochlearius cochlearius). The camera trap was installed on 20 February 2017 at 13:31 h. The white circle highlights the carcass of young Scarlet Ibis..

Abstract. With nocturnal and crepuscular habits, the Boat-billed Heron (Cochlearius cochlearius) is one of the least conspicuous species within the Ardeidae family. In view of the fact that data on its food ecology are scarce, our study provides evidence of an individual who has explored and possibly ingested part of the carcass of a Scarlet Ibis (Eudocimus ruber). The event documented took place in Parque Estadual Ilha do Cardoso, in the southeast region of Brazil, using a camera trap installed in a mixed colony which includes both Scarlet Ibis and herons. Finally, this study provides evidence of an opportunistic foraging behavior of Boat-billed Herons.

Abstract. The Great Pampa-Finch (Embernagra platensis Gmelin, 1789) is found in open areas in several countries of South America, at altitudes ranging from 500 m to 2500 m. It lives alone or in pairs, foraging while walking on the ground or in herbaceous vegetation. Its diet is predominantly composed of seeds and insects. In the present work, we present literature records of vertebrate predation by E. platensis and present a new record of anuran predation from Palmas-PR, southern Brazil. Literature data indicate that the species is recorded preying on amphibians and fish, albeit on a small scale, suggesting that the species behaves as an occasional predator. It is possible that these occasional sources of food are important to the species during times of scarce resources, such as during winter.

Abstract. The ‘Endangered’ Santa Marta Parakeet (Pyrrhura viridicata), endemic to the Sierra Nevada de Santa Marta in northern Colombia, faces a worst-case population scenario of only 500 individuals in total, within 210km2 of remaining primary forest. Since 2005 the Loro Parque Fundación and Fundación ProAves have worked together in Project Pyrrhura to prevent the extinction of this species. The project established the “El Dorado” Bird Reserve to protect a key area of subtropical to montane forest. The endemic wax palm, Ceroxylon ceriferum is essential in the life-cycle of the Santa Marta Parakeet, and details are given of nesting and roosting characteristics. The parakeet suffers a lack of natural cavities and a high level of nest predation and displacement. Artificial nests installed in the habitat have not yet demonstrated adequate compensation. The removal from habitat of exotic trees and reforestation with native plants is ongoing. To date, 33 food species of the parakeet have been identified, 80% of which are native. The relative frequency of plant parts consumed is given.

Abstract. The aim of this study was to evaluate the influence of macrophyte density and foraging strategy on the success of Pomacea predation by Snail Kite. Three vegetation density zones were defined and the success and failure rates as well as the strategies used were observed. Although foraging was distributed evenly across vegetation zones, the macrophyte density gradient did affect foraging strategy and capture success, but not as predicted. The kite had greater success in vegetation zones of increasing density, where sit and wait hunting mainly occurred, while less successful active hunting occurred mostly in the zone of lowest macrophyte density. In addition, we found that both vegetation structure and foraging strategy affect capture success. The results suggest that future studies may provide further information regarding the relationship between energy demand and energy return in this species. Why do the kites continue to carry out a method even without success?

Abstract. Until recently, artificial insemination (AI) in parrots (Psittaciformes) had limited success in very few species. Recent research has been conducted on the application of technological advances to broaden the use of AI as one element of assisted reproduction in parrots. Males were induced to produce semen by electrostimulation, each sample being immediately examined microscopically to evaluate sperm quality. The parameters of sperm quality are described. Comparisons between genera were made for semen production and sperm quality, and how these vary with season of the year. AI was performed on females by the introduction via capillary tube of fresh, evaluated semen into the oviduct. Assessment is made of the effect of when in the egg-laying sequence AI is performed. To improve the temporal and spatial application of AI in parrots, research was conducted on the cryopreservation of semen, the viability of unfrozen sperm and the effect of its use in AI. It is demonstrated that the use of electrostimulation to induce semen production has high success in parrots, including large species. Protocols for evaluation of sperm quality have been established. Clear differences in semen production and sperm quality are shown between genera, including on a seasonal basis. AI is demonstrated to be successful in a diversity of parrot species, including larger taxa. Protocols for viable cryopreservation of Nymphicus hollandicus semen are described, and successful AI of the same species using unfrozen sperm is demonstrated. It is concluded that AI in parrots is improved and broadened in its application by incorporating technological advances. It is recommended to continue research on all stages, with special attention to cryopreservation.
