Introduced house mice Mus musculus have recently been discovered to be significant predators of chicks Tristan albatrosses Diomedea dabbenena and several burrowing petrels at Gough Island. We summarize evidence for mouse attacks on albatross sub-Antarctic Marion Island, where are also the only introduced mammal following eradication feral cats Felis catus in early 1990s. Wounds consistent with found wandering exulans since 2003 dark-mantled sooty Phoebetria fusca 2009. To date, infrequent,...
Abstract Albatrosses are among the most threatened groups of seabirds with main land-based threats being alien invasive species, human disturbance and habitat degradation. Disease outbreaks in Antarctic sub-Antarctic seabird populations uncommon, but past few decades there has been an increase reported cases. The Prince Edward Islands (46°S, 37°E) south-western Indian Ocean provide breeding grounds for many including 44% all wandering albatrosses ( Diomedea exulans L.). In 2015, five two...
To conserve threatened species it is important to protect the most productive individuals in population, yet there little information on characteristics that distinguish such individuals. Among experienced Wandering Albatrosses (Diomedea exulans), we show current breeding performance correlated with previous success. By comparing birds unproductive and histories, test whether can differentiate more less successful breeders based body condition, arrival date attendance at colony during...
The Alabama Cave Shrimp Palaemonias alabamae Smalley, 1961 is a federally endangered cave shrimp endemic to just four systems within and near the greater Huntsville metropolitan area in Madison County, USA. It one of two described atyid Interior Low Plateau karst region. Here we report discovery new population P. from Fern system western Jackson Alabama. We observed August 2018 an isolated pool base-level stream passage longest Two were during subsequent survey July 2019: same second main...
Abstract A vagrant black-browed albatross Thalassarche melanophris bred with a grey-headed T. chrysostoma on Marion Island at least four times between 2000 and 2009 (and continued to return the colony until 2019). The eggs failed hatch in three breeding attempts, but pair fledged chick 2006/07 season. Genetic sexing identified as female she shared all eight sampled microsatellite alleles chick, whereas social parent did not match chick. fledgling was banded re-sighted its natal 2016 2018,...
The International Crane Foundation (ICF) / Endangered Wildlife Trust's (EWT) African Conservation Programme has recorded 26 403 crane sightings in its database from 1978 to 2014. This collection is currently ongoing and records are continuously added the by EWT field staff, ICF/EWT Partnership various partner organizations private individuals. dataset two peak periods: 1994-1996 2008-2012. spans five countries: Kenya, Rwanda, South Africa, Uganda Zambia; 98% of data were collected Africa....
In spring, large numbers of Golden Plover Pluvialis apricaria feed in lowland areas the Outer Hebrides, Scotland, and many these are presumed to be birds which breed Iceland. This study estimated how Icelandic pass through north Lewis, most northerly part island group. Birds were counted during spring 2005, samples scored on a scale 0–9 by boldness their plumage. Northern have bolder breeding plumage than southern forms. with scores 5–9 recorded early season believed altifrons form Locally...
