For example, the upright stance and depressed tail of the flycatcher, easily separates it from a warbler which usually perches with its tail forming a straight line with its back. Vireos, which look much like warblers, can be separated by the deliberate way they feed. They sit quietly, peering about and only moving when they find an insect.
Warblers are active, fluttering and darting about continuously as they search for food.
If a nest is found, keep a description of the nesting materials and the number and colour of the eggs, if any. This information may also help in identifying the bird. Different songbirds inhabit different habitats. Students should visit at least two different habitats so they can make this observation for themselves. Possible choices include forest edges, urban areas, fields around farms and near water bodies.
