The remige feather tracts are just barely indicated by a faint "shadow". Note: a hatchling from Nest #2 is same as above description and the down is pale gray." PAS [I found the following notes on a data sheet attached to data sheet for Chlorophonia cyanea. I'm sure the data belong with this series of Tersina] "18/IV/74. 10:30AM. Female on nest. I took the infertile egg (wgt 3gm) and the young. Wgt of yg = 8.5 gms. Still no pin feathers emerging from this yg.; primary tracts are visible as dark lines and secondaries also but less so. Still has down (pale gray): above each eye (coronal), on each side of occipital tract, on each scapular, on secondaries tract (= 2nd joint of wing), on dorsal tract and femoral tracts (both sides), on tract portion @ sides of belly; still bare traces on tail. Gen'l color orangish flesh; legs are paler now and just plain "flesh" color, claws ivory. Bill pale flesh; edge of gape white (ivory). Eyes not open yet (pupil can be seen through skin.) Bird had been recently fed and in crop a fairly large fruit w/ purplish skin and yellowish flesh, large seed; fruit has aromatic, pleasant odor (I backed out the fruit w/ my thumb.)" PAS
