Oklahoma Ornithological Society

-We examined Eastern Bluebird (Sialia sialis) nest box use at the Tishorningo National Wildlife Refuge from 1999 to 2002. In 1999,25 nest boxes were installed and monitored for use by all species during 2 nesting seasons. In 2001, we installed 20 additional nest boxes and monitored all 45 nest boxes for 2 mom nesting seasons. We monitored 178 bluebird nests with a mean clutch size of 4.5 eggs. ...

Washington Ornithological Society

Five new state birds revisited Dennis Paulson InWOSNEWS 30, I asked WOS members to submit a list of the five birds they predicted would be added to the Washington state list next. I also got the experts to reply to the same request. We eight "experts" of the Washington Bird Records Committee gave it our best tries (in fits of indecision, some submitted lists of more than five, but they were pru...

Mortality in Laysan ducks (Anas laysanensis) by emaciation complicated by Echinuria uncinata on Laysan Island, Hawaii, 1993.

In November 1993, unusual mortality occurred among endangered Laysan ducks on Laysan Island, one of the remote refugia of the Northwestern Hawaiian Islands National Wildlife Refuge (USA). Ten live ducks were emaciated, and blood samples documented anemia, heterophilia, and eosinophilia. Pathology in 13 duck carcasses revealed emaciation, marked thickening of the proventricular wall, abundant mu...

Multivariate Hybrid Visualisation of Ornithological Sensor Data

To overcome the challenges of displaying multivariate sensor data, we propose a novel work-in-progress, hybrid, polar method of visualisation. Sensor data is collected by marine biologists in high volumes and using multiple sensors. Challenges arise when trying to unlock the marine wildlife behaviour from the vast amount of time series data collected. The proposed method filters uninteresting b...
