Birds come in all shapes and sizes, and because of this, their diets can vary extremely. Larger birds need more substantial prey to support their requirements for energy, and unfortunately for frogs, they fit these criteria. So which birds eat frogs?
Many different species of birds will eat frogs and tadpoles. Wading birds such as herons, storks and egrets are commonly known to eat frogs, but other fishing birds such as kingfishers and members of the gull family will also eat them. It's less commonly known, but hawks, swans, geese, ducks, crows, ravens and owls will also consume frogs when given the opportunity to do so.
Buzzards will regularly take amphibians for food, and for some, this will make up a substantial part of their diets. On much rarer occasions, species like reed warblers, blackbirds, and blue jays will all eat frogs given the opportunity.
Habitat plays a big part in which birds will consume frogs, with birds that live in and around freshwater biomes eating a variety of frogs, both small and large - this will vary depending on the size of the bird.

Baby frogs, tadpoles and froglets are all consumed by many different species of birds. They are generally less evasive, and therefore much easier for the birds to catch, which makes them quick and easy targets for birds.
Many different types of birds of prey will consume frogs as part of their diets, this includes many different types of eagles, owls and hawks.
This is generally less frequently than other types of birds, but can still be a good source of nutrition, even to these bigger types of birds.
Generally speaking, birds will not eat any poisonous types of frogs, as it can be lethal to them and can result in their death. The bright colors and markings of a frog are essentially a message to predators that they aren't worth killing, as they are toxic - this is scientifically referred to as aposematic.
The majority of these frogs can only be found in parts of Central and South America in tropical climates. Birds in this part of the world know that the bright colors of these frogs are a signal not to eat, and they will avoid catching them.
Because frog eggs are tiny and do not provide much nutritional value to birds, which generally means they won't consume them. This isn't to say they never do, but they won't seek them out.
Other than birds, common threats and predators to frogs eggs include dragonflies, newts, diving beetles and leeches. There are also many other insects and water bugs that will consume the eggs of frogs, but these tend to be some of the biggest consumers.
Frogs will try and escape being eaten by either jumping into the water, camouflaging into their nearby surroundings. Some frogs will secrete bad-tasting chemicals on their skin and in their urine to avoid being predated.
Certain species of frogs will jump high up into trees to escape, which will keep them safe away from predators, however, this doesn't really work for birds.
Pretty much all frogs have powerful leg muscles, allowing them to jump quickly away into the water and escape becoming somethings next meal.
Some frogs are able to jump over 40 times the length of their body.
