Birding Trips:

These area activities are scheduled on various weekends and usually on a Wednesday or Thursday during the week. The field trips range from half-day outings to weekend trips to birding hot spots. Field trips are open to MDAS members and nonmembers alike. You do not have to be a birding expert: only one who enjoys nature.

Birding Trips -

Physical Difficulty
All our field trips are rated for physical difficulty:
Category 1: Easy, little or no walking, smooth paths.
Category 2: Moderate, 1 mile or more, possibly rough terrain.
Category 3: Difficult, extensive walking on rough terrain.

What to Bring?
It’s a good idea to bring a small backpack with rain gear, hat, sunscreen, field guide, and binoculars. We have a limited number of loaner binoculars available by calling the trip leader at least 7 days in advance. Some people like to take a drink and a snack to keep them going. Wear suitable shoes. Subdued colored clothing is preferable but not essential.

For full day outings take your lunch. Ask whether you will be returning to the cars for lunch. Many people also take a drink and a snack to have at the end of the walk.

What about Bad Weather?
Weather or the vailability of leaders may require changes. Trips go in light rain or drizzle. If in doubt, call the leader up to 1/2 hour before departure. If you are coming from some distance, call the leader and confirm departure point and time.

What about Transportation?
You can drive to the meeting point and carpool with the leader or other birders. Carpool expense are shared among driver and riders at the rate of 20 cents per mile; tolls and entry fees are shared equally by driver and riders.

In the directions, the term “carpool time” refers to the actual time that the participants depart from the meeting site.

Local Check Lists:

Bird Banding:

Banded birds can be occasionally seen upon close examination. These birds are being tracked for scientific purposes by a variety of sources. These two links include information about how to report banded birds.

Birding Ethics:

Before advertising the presence of a rare bird, evaluate the potential for disturbance to the bird, its surroundings, and other people in the area. Proceed only if access can be controlled, disturbance can be minimized, and permission has been obtained from landowners. The sites of rare nesting birds should be divulged only to proper conservation authorities. In any conflict of interest between birds and birders, the welfare of the birds and their environment comes first.
