It is the curse of the nature photographer to alternate between moments of great activity interspersed with long intervals of waiting. Today the intervals were prolonged, but thankfully the other photographers were pleasant and soaking up the warm sun was a welcome change from the extended cool spring.
When there are birds overhead, it is always interesting. Will they see fish to catch? Will they be successful? Will they be able to hold on? Photographers like fishermen regret the ones that get away.
Sometimes during the lulls in the action there are other subjects around. Several eagles visit the area. After all stealing a fish from an Osprey is so much easier than catching one yourself. They are both juveniles and full grown adults. Of course if something opportunistically presents itself, either fish or fowl, it's worth making an effort.
There are always opportunities to sharpen your skills on the gulls. Their slow motion flight good practice fo acquiring and focusing on your subject. When one gets a fish you better be quick, because it is swallowed quickly. Failure to do that results in all the the other gulls trying to grab the catch, like some jealous two year child that doesn't know how to share.
