Breeding avifauna of the south San Francisco Bay estuary Breeding avifauna of the south San Francisco Bay estuary

San Francisco Bay represents one of the largest estuarine areas on the Pacific Coast of North America. Its open waters, tidal flats, tidal marshes and solar evaporation ponds provide critical foraging, resting and breeding habitat for migratory and resident birds. The avifauna of San Francisco Bay has received considerable attention; however, little of it has been directed toward...

Unusual foraging by a fork-tailed storm-petrel Unusual foraging by a fork-tailed storm-petrel

While conducting an offshore bird census from the sea beach at Nelson Lagoon, Alaska Peninsula (56°00'N, 161°10'W) at 1700 on 17 September 1976 1 saw a Fork-tailed Storm Petrel (Oceanodroma f. furcata) feeding on the beached remains of an adult gray whale (Eschrichtius robustus) that had been trapped by ice and died the previous April. I watched it for about 15 min. The sky was overcast...

Radiometric dates from Alaska: A 1975 compilation Radiometric dates from Alaska: A 1975 compilation

The following table of radiometric dates from Alaska includes published material through 1972 as well as some selected later data. The table includes 726 mineral and whole-rock dates determined by the K-Ar, Rb-Sr, fission-track U-Pb, and Pb-alpha techniques. The data are organized in alphabetical order of the 1:250,000 scale quadrangles in which the dated rocks are located. The latitude...

Radiometric age map of southwest Alaska Radiometric age map of southwest Alaska

This map includes published, thesis, and open-file radiometric data available to us as of June, 1975. Some dates are not plotted because of inadequate location data in the original references. The map is divided into five sections, based on 1:1,000,000 scale enlargements of the National Atlas maps of Alaska. Within each section (e.g., southeastern Alaska), radiometric dates are plotted...
