Event Remarks |
Viewing Conditions: Distance: I can only estimate that it was between 300 and 400 feet from my viewing point on the shore. Optical equipment: I could see the bird very well through Bushnell 7 x 35 Wide-angle binoculars but I studied this bird carefully through a Baush & Lomb Spotting Scope on 30 power. It could be seen almost equally as well on both 15 and 20 power hoever [sic]. Light: I was facing east as I was studying the bird, the afternoon sun was to my back which provided very good lighting conditions. |
