Description:

Abstract:

Crested (Aethia cristatella) and Least Auklets (Aethia pusilla) are crevice-nesting birds that breed in large mixed colonies at relatively few sites in the Aleutian Chain, Bering Sea, Gulf of Alaska and Sea of Okhotsk. Time-lapse imagery of nesting habitat was collected over the summers of 2010, 2012, and 2013 to assess use of the primary pre-eruption colony site. At-sea surveys collected relative abundance data to identify shifts in distributions of Crested and Least Auklets around Kasatochi and Koniuji Islands.

Purpose:

To provide data on presence/absence data on Crested and Least Auklets at the primary Kasatochi colony site. At-sea data was collected to test for changes in the relative abundance and spatial distribution of crested and least auklets around Kasatochi and nearby Koniuji Islands.

Methodology_Description:

At-sea surveys were conducted using standard protocols. Two observers identified and counted birds along a 300m wide strip transect. Densities were calculated as #birds/sampled area in square km.

Methodology:

Methodology_Type: Field
Methodology_Description:

A time-lapse camera with a Canon 50D and a 25-105 lens at 100mm collected images of the old colony site every 15 minutes.

Process_Step:

Process_Description:

DSLR Images fom the Canon camera were processed in Photoshop to overlay a 24 cell grid and images that were obscured due to weather or low light were not analyzed.

Process_Date: Unknown

Process_Step:

Process_Description:

At-sea density calculation- Survey area in square kilometers was generated for each survey transect based on transect width. Density calculations were made by dividing the recorded number of observations for each species by behavior and survey area in square kilometers. Behavior was split so researchers could select only birds on the water or combine these classes.

Overview_Description:

Entity_and_Attribute_Overview:

The SlopeGrid_Presence-Absence table provides data on the attendance of crested or least auklets on the Tundering Talus colony site after the eruption. We overlayed a 24 cell grid over each image and used the total as a measure of "attendance" on the slope. The At-Sea_Survey table provides survey information including transect ID, survey area, species, number observed, density, and transformed (log base 10) density.
