Grey Wagtail Habitat and Size

Grey Wagtail: A Waterside Dweller
Habitat: Grey wagtails are typically found in areas near running water. They prefer habitats such as:  

Rivers: They are commonly seen along the banks of fast-flowing rivers, especially in upland areas.  
Streams: Smaller streams and creeks can also provide suitable habitats for these birds.
Lakes: Grey wagtails may also be found around the edges of lakes, particularly where there are shallow areas with plenty of insects.  
Man-made structures: They are adaptable and can often be found near canals, ponds, and even water features in urban areas.  
Diet: Grey wagtails are insectivorous, meaning their diet primarily consists of insects. They are skilled hunters and can be observed foraging along the water's edge or on nearby rocks and vegetation. Some of the insects they commonly consume include:  

Aquatic insects: Mayflies, caddisflies, and stoneflies are often found in their diet.  
Flying insects: Flies, gnats, and mosquitoes are also important food sources.  
Terrestrial insects: Ants, beetles, and spiders may be consumed, especially when they are found near the water's edge.
In addition to insects, grey wagtails may also occasionally consume small aquatic invertebrates, such as snails or tadpoles.
