North American Birding Trails

Since their inception in 1996, birding trails now wind throughout the United States. Texas was the first of now almost 40 states to create birding trails. The trails were the inspiration of Ted Eubanks and Madge Lindsay. Their inspiration resulted in the first trail, the Great Texas Coastal Birding Trail. The list continues to grow as birders and other nature lovers discover this great way to enjoy our wildlife resources.

The trails are created using existing highways, byways and county roads to link prime public and private birding areas. Distinctive signs mark the way and detailed maps are available for each of the trails (some are free and some have a small charge). Both can be a big help to birders unfamiliar with an area.

Expert birders and beginners alike are drawn to the trails. A boost to local economies and a boon to birds – birding trails are a win-win situation for all involved. Not only do birders spend money while traveling along birding trails, the trails also help communities become aware of the treasures they may have in their own back yard – and the need to protect those treasures.

The National Audubon Society and the American Birding Association both have extensive lists of birding trails on their web sites. Plan a birding road-trip to somewhere you haven’t been in a while or explore someplace totally new to you. Discover and enjoy what our wildlife resources have to offer.

Please do your part - keep your frickin' cat indoors!

The number of songbirds killed by cats each year is significant. This problem will worsen if left unchecked. Even well fed domestic house cats when left outside will kill birds. Cats hunt out of instinct even when not hungry. Even declawed cats are effective hunters and it is widely know that a bell on a cat’s collar is no deterrent.

Consider this: it is typical for a domestic female cat which is kept indoors to become sexual mature at five to nine months of age. A free roaming cat can become sexually active much sooner than that. Cats from the same litter can mate and female cats, especially in milder climates, can become pregnant any time of year. The average gestation period of a cat is under 70 days and the litter size ranges from three to six (or more) kittens. It is not uncommon for cats to go back into heat one to two months after giving birth - some sooner. Cats can have up to five litters per year. This would give just one female cat the potential to have 15 to 30 kittens (or more) per year. The cycle starts over again when these kittens become sexually mature in five to nine months. You do the math…

There are an estimated 60 million or more pet cats in the United States (this does not include the millions of strays and feral cats). Studies show the percentage of cat owners that allow their cat outside to be conservatively 25% or more. Cats allowed outdoors are not only a threat to birds but also at risk themselves (example: car vs. cat = car winning nearly every time). Neither of these losses is necessary.

The American Bird Conservatory’s citizen education and action program Cats Indoors! encourages responsible cat ownership. You can find recommendations on how you can help on their website. The National Audubon Society has passed a Resolution on Cats supporting the need for action.

Please do your part - keep your cat indoors!

Birding By Ear

Birding by ear is at the apex of birding skills. It is the goal of birding by ear to separate one song or call from another, and then determine which species is making the sound. It is probably one of the best skills a birder can develop. Birding by ear is an essential skill for paid birding guides, or anyone who studies or surveys birds.

We've all birded with someone who is able to distinguish between an eastern and a western meadowlark just by hearing it. Or someone who is able to identify half a dozen birds before leaving the parking lot when the only thing that's flown by is a black vulture.

If you know someone who has a mastery of birding by ear, accompanying them in the field is a great way to gain insight into the world of bird songs. It sometimes take a very discerning ear to point out subtle differences that a novice might miss.

Sometimes mnemonics is a useful tool in learning bird songs. Mnemonics is accomplished by translating the bird sounds and calls into human speech. "Who cooks for you?" for the Barred Owl, "teakettle, teakettle, teakettle," for the Carolina Wren, "what-cheer, what-cheer, what-cheer," for the Northern Cardinal, etc.

Perhaps the key to learning to bird by ear is repetition. Luckily, we live in the age of mp3 players (such as an IPod, etc.). Not only can you load hundreds of bird sounds and listen over and over in the comfort of your home, the small, lightweight devices can easily be carried into the field, supplementing your learning experience there.

Learning bird songs and calls takes time and patience. Some are easy to remember while others, like migrating warblers, are more challenging. Keep trying and your skills will improve rapidly. Above all else, enjoy yourself and enjoy the experience of being in the moment birding!

American Birding Association's Code of Birding Ethics

Tricoloured Heron, Birding Center, Port Aransa...Image via Wikipedia

Everyone who enjoys birds and birding must always respect wildlife, its environment, and the rights of others. In any conflict of interest between birds and birders, the welfare of the birds and their environment comes first.

CODE OF BIRDING ETHICS

1. Promote the welfare of birds and their environment.

1(a) Support the protection of important bird habitat.

1(b) To avoid stressing birds or exposing them to danger, exercise restraint and caution during observation, photography, sound recording, or filming.

Limit the use of recordings and other methods of attracting birds, and never use such methods in heavily birded areas, or for attracting any species that is Threatened, Endangered, or of Special Concern, or is rare in your local area;

Keep well back from nests and nesting colonies, roosts, display areas, and important feeding sites. In such sensitive areas, if there is a need for extended observation, photography, filming, or recording, try to use a blind or hide, and take advantage of natural cover.

Use artificial light sparingly for filming or photography, especially for close-ups.

1(c) Before advertising the presence of a rare bird, evaluate the potential for disturbance to the bird, its surroundings, and other people in the area, and proceed only if access can be controlled, disturbance minimized, and permission has been obtained from private land-owners. The sites of rare nesting birds should be divulged only to the proper conservation authorities.

1(d) Stay on roads, trails, and paths where they exist; otherwise keep habitat disturbance to a minimum.

2. Respect the law, and the rights of others.

2(a) Do not enter private property without the owner's explicit permission.

2(b) Follow all laws, rules, and regulations governing use of roads and public areas, both at home and abroad.

2(c) Practice common courtesy in contacts with other people. Your exemplary behavior will generate goodwill with birders and non-birders alike.

3. Ensure that feeders, nest structures, and other artificial bird environments are safe.

3(a) Keep dispensers, water, and food clean, and free of decay or disease. It is important to feed birds continually during harsh weather.

3(b) Maintain and clean nest structures regularly.

3(c) If you are attracting birds to an area, ensure the birds are not exposed to predation from cats and other domestic animals, or dangers posed by artificial hazards.

4. Group birding, whether organized or impromptu, requires special care.

Each individual in the group, in addition to the obligations spelled out in Items #1 and #2, has responsibilities as a Group Member.

4(a) Respect the interests, rights, and skills of fellow birders, as well as people participating in other legitimate outdoor activities. Freely share your knowledge and experience, except where code 1(c) applies. Be especially helpful to beginning birders.

4(b) If you witness unethical birding behavior, assess the situation, and intervene if you think it prudent. When interceding, inform the person(s) of the inappropriate action, and attempt, within reason, to have it stopped. If the behavior continues, document it, and notify appropriate individuals or organizations.

Group Leader Responsibilities [amateur and professional trips and tours].

4(c) Be an exemplary ethical role model for the group. Teach through word and example.

4(d) Keep groups to a size that limits impact on the environment, and does not interfere with others using the same area.

4(e) Ensure everyone in the group knows of and practices this code.

4(f) Learn and inform the group of any special circumstances applicable to the areas being visited (e.g. no tape recorders allowed).

4(g) Acknowledge that professional tour companies bear a special responsibility to place the welfare of birds and the benefits of public knowledge ahead of the company's commercial interests. Ideally, leaders should keep track of tour sightings, document unusual occurrences, and submit records to appropriate organizations.

PLEASE FOLLOW THIS CODE AND DISTRIBUTE AND TEACH IT TO OTHERS

Birding With Field Notes And Sketches

To what extent you take field notes when birding is a matter of personal choice. The goal of using field notes varies among birders. Birding field notes range from a list of birds seen on a particular day at a particular place - to observing birds for the purpose of identification and/or the collection of data, using habitat, time of year, voice, markings, color, size, posture, how the bird flies and anything else that will help you in the endeavor. So, the first step in taking field notes is to make a conscious decision what you want to record.

For instance, if your goal is to ID a bird, consider using this field noting technique. After observing the bird and before opening your field guide do two things. 1) Immediately write down what you see (there is really a reason short term memory is called “short term”). 2) Accompany your notes with sketches. No matter how rough the sketch, drawing forces you to observe detail. Don’t waste time flipping through your field guide when you could be observing the bird and noting detail!

When finished writing and sketching, now open your field guide and try to match what you’ve written/sketched with the description given by the guide. If the bird is still around, look for any markings or characteristics the book mentions that you may not have noted.

Lastly, the only person that will see your field notes is you unless you choose to share them. Don’t be concerned about spelling or grammar and don’t be concerned about a lack of writing or drawing ability. When is the last time you heard someone say, “He has the bird ID correct but just look at that dangling participle!” Happy birding.

The Remarkable Sounds of Birds

Until the British musician David Hindley studied the song of the Skylark by slowing it down the song was simply regarded as just another beautiful bird song. But what he discovered was that the bird song held recognizable musical notes! From forty eight seconds of the compressed and mind numbingly complex song, Hindley extracted nearly thirteen minutes of sheet music - music that could be played like any other piece. But even more astounding was the remarkable resemblance to structures in Beethoven's Fifth Symphony!

The vocal skills of birds are due in part to the unusual structure of their vocal anatomy and are decidedly more complex than a human’s. The bird’s equivalent to the human sound box is called a syrinx. The two part syrinx is located deep within the bird’s chest at the junction of the air tubes that lead from the lungs. Each half of the syrinx is attached to one of the two different air tubes giving it the ability to produce two different notes at the same time.

Birds use this incredible ability when searching for a mate, when defending and declaring a territory, or to maintain the bond of a pair. For these reasons, males usually are more vocal than females with spring being the most vocal season. Dawn is the bird’s most vocal time of day. Scientists are still not sure why birds seem to prefer dawn but it is characteristic of birds worldwide.

We still have many things to learn from our avian friends. But not knowing all the answers, thankfully, doesn’t keep us from enjoying the sites and sounds of birding!
