Yes, grey herons do migrate, although their migration patterns can vary by region. In northern Europe, many herons migrate south during the winter to find warmer conditions and more abundant food sources. However, in milder climates, some grey herons may remain resident year-round. Migration typically occurs in response to changes in temperature and the availability of food.

In general, ducks and blue herons do not interact much with each other unless there is competition for resources such as food or nesting sites. Blue herons are known to be aggressive towards ducks if they feel threatened or if they perceive them as competition. Ducks may try to avoid blue herons to minimize conflict.
Herons are birds.
Information about the Great Blue Herons can be found in various bird encyclopedias or from various ornithologist websites, which generally cover a lot of birds.
Foxes are opportunist hunters, and will take a young or injured bird when hunting for food.
