Eyas Falcon Eye Us Noun Unfledged Bird Specifically Nestling

[By erroneous splitting of the original "a nyas" into "an eyas". From Latin nidus (nest), ultimately from the Indo-European root sed- (to sit) that is also the source of sit, chair, saddle, soot, sediment, cathedral, and tetrahedron.]

"One of the three peregrine falcon chicks nesting atop downtown Seattle's Washington Mutual Bank died early Wednesday. A wildlife expert who spotted the struggling eyas freed it and then transported it to the Woodland Park Zoo." - Marc Powell; Ailing Falcon Chick Dies in Seattle; The News Tribune (Tacoma, Washington); Jun 30, 1994.
