The breeding season has finished for now. We had a lot of work and want to share with you some of our results.
Between August and December 2013 we have concentrated our efforts on the reproductive biology and ecology on the Blue-fronted Amazon and other local psittacine species (all but macaws), at the Caiman Ecological Refuge and the Novo Horizonte farm (both in Miranda, Pantanal). The specific objectives of the Blue-fronted Amazon Project were: to characterize nests and nesting habitats; to estimate the size and survival rate of the offspring; and to close monitor the parental care with eggs and nestlings of Blue-fronted Amazon and other local psittacine species (all but macaws).
Our results: we have monitored 72 tree cavities, including some previously used by Blue-fronted Amazons. From those, 49 (68%) had signs of nesting activity, such as one or two adults in the cavity, the presence of feathers in the cavity, and scratching marks on the entrance. Thirty-one (43%) of the cavities were actually used as nests, as shown by the presence of at least one egg and/or chick. The nests were in 16 different tree species, from 9 families, with different dimensions, and the cavities had variable characteristics. The oviposture and incubation occurred between August and September. A total of 53 eggs were laid; 35 (66%) of them hatched, while 18 (34%) were either predated or did not hatch. The clutch size varied from one to tree eggs per nest, but 2- and 3-egg clutches were much more frequent. The eggs hatched between September and October, and nestlings varied from 1 to 3 (although 2 were more common). From the 35 nestlings that hatched, 25 of them fledged and 10 died (mortality rate among nestling was 28,5%).
We have also done many environmental education activities in 2013, aiming to raise awareness among kids and teens about the illegal animal trade, through out puppet theatre and the project E-CONS (Empreendedores da Conservação – SPVS-HSBC). And we have shared all our activities and results with local communities, general public and the scientific community.
We want to thank everyone who worked hard with us in 2013: Anne Zugman, Anne Galvão, Cecília Brosig, Danilo Ferreira Seixas (in memorian), Giana Alves Correa, João Augusto Albuquerque Soares, Marja Zattoni Milano, Mariza Silva, Vandir Fernandes da Silva, and Victor do Nascimento.
We also want to express our most sincere gratitude to our partners and collaborators: Parque das Aves – Foz do Iguaçu – PR; Refúgio Ecológico Caiman – Miranda – MS; Programa Econs – SPVS/HSBC – Curitiba – PR; Alouatta Criações – Corumbá – MS; Companhia das Artes – Campo Grande – MS; and Centro de Reabilitação de Animais Silvestres (CRAS)/Instituto de Meio Ambiente de Mato Grosso do Sul (IMASUL) – Campo Grande – MS.
