Nesting tree selection by scattered heronry birds of drought prone Northern Bankura, West Bengal, India: preference of Phoenix sylvestris near wetland-associated habitats

The present study was conducted in the Gangajalghati block of Northern Bankura, India, to investigate the habitat and nest tree preference of three colonial waterbirds viz. Nycticorax nycticorax, Egretta garzetta, and Ardeola grayii. The study sites were surveyed for 20 months between 2017 and 2020. A total of 817 nests with an average of 204 per year were recorded on 13 tree species. Nycticorax nycticorax showed the maximum nest count followed by Egretta garzetta and Ardeola grayii. Relative abundance data revealed Phoenix sylvestris as the most abundant species (45%) of the area and harbours the highest proportion (33%) of nests. Pooled nest count data showed significantly higher (p < 0.01) total nest counts in the wetland associated habitats than others. The study observed more nest density of all three species near a cluster of small ponds than in a large water body. Year-wise difference in cumulative nest number and mean nest abundance of all three species was statistically insignificant. The interspecific nearest neighbour on Phoenix sylvestris were Egretta garzetta (88.37%) for Nycticorax nycticorax and Nycticorax nycticorax (83.25%) for Egretta garzetta and Ardeola grayii. Further, the study evaluated the impact of two tropical cyclones (Amphan and Fani) on the total nest count and found that more than 75% nests (p < 0.05) were destroyed by the mighty Amphan in May 2020. The study provides a baseline data on nesting trees and habitat preference of three species of heronry birds from Northern Bankura.

First Provincial Record of Black-crowned Night heron (Nycticorax nycticorax) in West Sumatra and the Summary of Its Sumatran Records

The Black-crowned Night heron (Nycticorax nycticorax) is a known visitor in Sumatra with more sighting records in the eastern side of the island. Meanwhile, on the west, it was historically recorded from only two offshore islands, namely Nias and Enggano. During the waterbird survey from early 2018 at Pasir Jambak Beach of Padang City in the coastline of West Sumatra, a Night heron was spotted among the colony of mixed egret species. This is the first record of its kind in the province of West Sumatra, although, previous records cover almost all provinces in Sumatra. The summary of the compiled records of this species indicates that it is probably a vagrant along the western coastline, while it visits more frequently on the eastern side.

Pathogenicity of Two Nematodes Tetramerese sp. and Microtetramerese Spiralis in Proventriculus of Some Aquatic Birds from Al-Sanaf Marshes in Thi-Qar Province, South of Iraq

The present study was carried out to investigate the prevalence and mean of intensity of two nematodes Tetramerese sp. and Microtetrameresespiralis isolated from some of aquatic birds collected from Al-Sanaf marshes, Thi-Qar province.The pathological effects of these parasites on the tissues of the infected aquatic birds were recorded.TheTetramerese sp. females were embedded in glands of proventriculus of the some aquatic birds including: Ardea ralloides, Egretta garazeta, Nycticorax nycticorax, Himantopus himantopus, Larus genei, Bubulicus ibis, Aredea purpurea and Anas clypeata with prevalence 12.57% and mean of intensity 3.00, while the Microtetrameresespiralis embedded in gastric glands of proventriculus of Bubulicusibis with prevalence 10% and mean of intensity 25.00.Histopathological examination of infected tissues showed dilation of the proventericular gland lumen, atrophy, necrosis and degeneration of the glandular cells of proventriculus

Artificial Wetlands as Breeding Habitats for Colonial Waterbirds within Central Romania

The historical loss of natural wetlands in Romania is significant. The building of lakes, ponds, and dams has compensated for some of these losses, as was the case in the study area, the artificial wetlands designated as the Natura 2000 (special protection area, SPA) and Ramsar sites. In this context, to evaluate the conservation status of colonial waterbirds (cormorants, herons, and egrets), we analyzed actual distributions, habitat selection, features, and population sizes. Standardized counting of colonial species was used, supplemented by nest counting and colony-area estimation during winter, and drone footage. All species and their colonies were built in artificial or anthropically influenced habitats. Concerning distribution and population sizes, Phalacrocorax carbo and Microcarbo pygmeus were found to nest only in central Romania. The pair numbers of Ardea alba, Ardea purpurea, Ardea cinerea, and Nycticorax nycticorax in the area exceeded 1% of the national minimum breeding population. There was a statistically significant positive trend of breeding populations for Ardea alba, Nycticorax nycticorax, and Egretta garzetta. In conclusion, these artificial wetlands offer optimal breeding conditions for a relatively large diversity of colonial bird species over areas that are not very large.

CAPILARIASIS EN GARZA HUACO COMÚN (NYCTICORAX NYCTICORAX)

Nycticorax nycticorax é uma ave da família Ardeidae. É cosmopolita e com ampla distribuição mundial e as infecções parasitárias estão entre os problemas sanitários mais comuns que as afetam. Este relato objetiva descrever o tratamento parasitário em um savacu com capilariose, em internação no Núcleo de Conservação e Reabilitação de Animais Silvestres -Preservas/ UFRGS, Brasil. Dados sobre tratamento são escassos nesta espécie. O animal era de vida livre, proveniente do Campus Universitário da UFRGS e foi trazido ao hospital por populares. Capillaria spp. foi diagnosticada por dois métodos coprológicos. A ave foi medicada com levamisole (20 mg·kg-1, subcutânea, dose única). Este relato reflete a importância do tratamento devido a patogenicidade da capilariose e para suprir uma lacuna quanto ao principio ativo que apresente efetividade terapêutica.
