Will an osprey eat baby seagull and ther eggs?

Yes, an osprey may eat baby seagulls and their eggs if given the opportunity. Ospreys are opportunistic predators that primarily feed on fish but will also take advantage of other available food sources, including small birds and their nests. The likelihood of this occurring depends on the availability of food and the specific circumstances in the environment. However, such predation is not a primary behavior for ospreys.
