Birding Tips and Ethics
Experienced birders confidently identify birds by just a glimpse. If you are new to the hobby, think of it like identifying new people you meet. You observe their characteristics, like size, shape, and walking behavior, as well as the place you saw them, as identifiers. Birders use silhouettes, posture, flight pattern, size, and habitat to recognize different avian species.
Start by keying in on a general group or family of birds, such as warblers, flycatchers, hawks, owls, and wrens because all members of a group share certain similarities. As a next step, notice the field marks, which are colored or patterned places on a bird’s body, head, and wings. Remember that a bird’s feathers, or plumage, change over time as a juvenile bird molts into its adult plumage or an adult molts into its breeding plumage. In most cases, the colors and behaviors of the male attract a female for mating purposes.
Carrying the right equipment is key for successful birding. All you need is a pair of binoculars, a field guide, a pocket notebook, and the patience and willingness to learn. No matter what pair of binoculars you own, practice looking through them so that you are not scanning wildly for a bird through the trees. First spot a bird with your eyes, and then lift your binoculars to your eyes without moving your head or losing sight of the bird. Becoming familiar with your field guide by interpreting the range maps, learning the terms for various field marks, and the species arrangement will help you more quickly identify birds. In your notebook, you can record your observation (species, date, location, and observers), and any other notes, such as behavior or weather).
And, listen, really, listen. Identifying birds by ear is essential for improving your birding techniques. Expert birders can identify thousands of songs. The late American ornithologist Ted Parker could identify about 4,000 species by ear. Bird songs, which can be quite elaborate, are used to attract a mate or defend territorial boundaries; calls are used to find family members, announce the approach of a predator, or share information about food sources. The more time spent observing birds calling and singing, the more quickly your memorization skills will improve over time.
Responsible Birding in Yosemite
Yosemite National Park’s scientists ask that you respect and help protect Yosemite’s birds by following these rules when birding in order to avoid a negative impact on the park’s birds.
1. Do not use any audio or mechanical device to attract birds and other wildlife (Code of Federal Regulations). State law strictly prohibits broadcasting recorded vocalizations of an endangered species, such as the great gray owl (California Code of Resources). The use of such devices may induce stress and disrupt mating/nesting activities of wildlife.
2. Do not view birds or other wildlife with a flashlight or spotlight (Code of Federal Regulations).
3. Do not divulge locations of any special status species observed in the park, particularly distribution over the Internet.
Note: The National Park Service is authorized to withhold information about endangered, threatened, and rare species in order to protect the species and their habitats from harm (National Parks Omnibus Management Act).
Violation of federal regulations may result in a fine of up to $5,000 and/or up to six months in jail.
Did You Know?
Riparian communities are adjacent to the river channel and tributaries; they are the interface between the river and surrounding meadow and upland communities. They provide specialized habitat and important nutrients to the meadow and river systems.
