Mahu 1959 Electrophorus mivalis. June 24 a female Longspine landed between her nest— She at once flew + landed on next side of Longspine + then chased Longspine. Later while I was taking pictures both ♂ & ♀ chased a ♂ Longspine. As I recall the ♀ took initiative. July 4 Nest, along river in bluff 5 ft above river edge in crack in rock 5" wide 18" deep. Partly old—had been used before—contained 4 eggs, 2 chicks, & one stone. July 22 The above nest chicked again on the 21. Empty. However, there is a loose pile of rocks about 20 feet from nest + it appears the young + adults are still hanging about that cover. Many droppings about the pile. Flushed one adult & one chick from it. July 24 Female hunting seen carrying a mouth full of food. In neighborhood of nest noted July 4 above. Could be the young are still dependent + being fed. Likely. July 25 ♂ hunting feeding 2 flying chicks along bank at mouth of Leon Stough.
