I wonder about the dark/black spot on this evening's osprey's forehead - in last year pictures Iiris did not have that deep and dark spot on her head. Iiris' head had more stripes, not such a covering dark spot ...
Owlie, the trouble is this year's blurry focus of the camera.. It would have been so much easier to compare the stripes and patterns, had the focus been sharp.
Yet it is not, and we have to take into account that that also distorts the picture. It can be that were we saw clear black stripes last year, now it is all blurred in one darker spot.
One cannot exactly compare a picture that is very sharp and one that is blurred.
Hopefully the camera will be re-adjusted. But we can see the differences/similarities in general aspects. Like, noticing here or there a brighter area, some stripes, overall shape and look etc.
All in all, ospreys are not all so similar at all, as it may at first seem
And the overall look of the osprey, also from the picture earlier with the slightly bent head, looking down at the nest.. It is so similar and it seems to be the same osprey, Iiris!
Also, even though strange ospreys sometimes do visit and land on the nest, on average, the probability is quite large that exactly the owner returns to his/her nest. If she then rather quickly accepts Ivo, we will know for sure
But Sunshine has some good arguments...
