Thank you all for your interest. I have been back to the exif on this picture which might be of the Tanager family and from the date and time (9 a.m. om 15th May) it is probably somewhere around the Canopy Tower area (Later that morning I photographed the Miraflores Locks). Hope this helps.
I put up a sunflower head in the woods (Bedfordshire) where I have a few feeders. The Marsh Tit is a regular visitor and soon found the seed head. I didn't know that they picked a seed, but it between the feet, extracted the heart and only then ate the food. For me this is interesting.
