Note: Owner Information Source

PreColumbian Master; Panama Gold

Note: Object Description

Small solid cast bird pendant with single suspension loop on back, large flat headdress, closed hooked beak, and ball eyes.

Note: Owner Accession

Collected by McNiel by 1883

Note: Research Notes

Find info on McNiel excavations

Note: Condition Review

Missing corner of proper left side of headdress and tip of PL tail, possibly taken as samples as the break edges are fairly regular and straight. There is also a small amount of loss at the PR tip of headdress and PR tail which are smaller and less regular. There is a small gouge in the front of the PL shoulder that has developed some black corrosion. A star symbol is painted on back in white and red

Note: Follow-up Notes

Special. Definitely analyze by ESEM as it is small enough to fit in chamber, there are excellent cross-sections to analyze, as well as areas of different color, dendrites on the surface, and it is in very good condition (minimum corrosion)

Note: Analysis Recommendations
