October 21, 1958
Washington Zoo

There are two of these Golden Spider Monkeys here, in a cage with a single Woolly Monkey, and one Panama Black Spider Monkey ([[underlined]] fusciceps. [[/underlined]])

[[Image - three red vertical lines and a red rectangular shaped hashed section in left margin of page]]

They Hdd just like the [[underlined]] fusciceps [[/underlined]]. Also pucker their lips in the same way. Both obviously hostile responses to me.
When I first approach their cage, however, they give another reaction. Usually Hdd-ing, or sleeping (?) before I approach, then lift head as I get nearer, and utter a distinctive call. Poly syllable or multi-note. Usually comme ca : [[image - three short horizontal lines, a fourth, longer line lifting slightly]] or [[image - two short lines with a third longer line lifting slightly]] Quality of each note high & thin. Rather like the Squ or [[Till?] of the Capuchin at BCI or the Black Spider, [[underlined]] fusciceps. [[/underlined]]. This is obviously homologous with part of the Squ-[[Till?]]-B complex of the Black Spiders, but I don't know which yet. Probably the [[Till?]] ??? Most reminiscent of the [[Till's?]] of the S Black Spider I had at BCI. Obviously contains a strong escape component, as the Golden Spiders immediately go back into the Hdd after giving their call.
