Thanks for the great closeups of Bea and Jasper and the explanation about their different looks. For my untrained eye, the speckled breast would be the clue that I would be looking at Bea. She seems to be doing a real "motherly" job caring for her eggs and, while I don't see much of Jasper, he must be doing his part too. Can't wait for the little ones to hatch!

thanks for posting the closeups of the O pair :-)
I've noticed ospreys have from one/two to several spots on their body. These can be seen whenever they lift their wings.
Could these be considered as another way to ID a particular bird besides their head markings?

Yes they can.

Below is an excerpt from the http://neotropical.birds.cornell.edu web site:

Adult (Definitive Basic plumage): Forehead, crown and nape white, spotted with blackish brown (markings heavier on center of crown and nape). The eye is surrounded by a blackish brown ring, which then expands behind the eye in a wide blackish brown band that extends along the side of the neck to the back. Underparts mostly white, other than for a variable amount of dusky streaking on the sides of the throat and across the breast. The back, scapulars, rump, and upper surface of wing are dark brown; the primary coverts are almost as dark as the primaries. Upper surface of rectrices medium brown on outer webs; inner webs of all but the central pair are duller whitish. Rectrices crossed by about 5 (central rectrices) to 8 (outermost rectrices) dark brown bands, the most distal of which is the widest. The rectrices are tipped dull white.

Underwing coverts white, heavily barred or marked dark brown on greater secondary-coverts and the distal portion of the median secondary-coverts; the dark coverts on outer half of under wing surface form a conspicuous dark carpal-patch. Remiges dull whitish, barred with medium brown, and becoming darker on distal, narrowed portion of outermost 5 primaries. Axillaries brownish white and often with darker terminal marks.

The dark feathers of the nape, sides of neck, and anterior crown are elongated, forming short frontal and nuchal crests when erected.

Sexes are similar, except that the dark markings on chin, breast, and sides of neck average greater in females than in males; some males may appear all white in these areas or have minimal dark markings.
