A Guide to Various Wild Bird Dietary Requirements

CHIMNEY SWIFTS
If you are fortunate enough to have these birds in your chimney, consider yourself very fortunate. They will return each year about April, have their babies about June, and leave the end of September, eating thousands of flying insects each day. The flock flies in large circles in the air with their mouths open, catching insects in flight. If you hear them in your chimney in the spring, close the damper so that they do not end up in your fire box and eventually into your house. These birds are very difficult to rehab. because they eat on the wing, so both babies and adults must be hand fed as long as they are in captivity. Their diet is a strictly insectivore diet. They cling to the side of the chimney, not perching like most birds, so they will need a tall basket lined with a towel to simulate their habitat in the chimney. They shake their heads vigorously making it difficult to feed them, but with a little patience you will soon get the hang of it. Their release should be at dusk, placing them on the side of a tall utility pole, tree, or even the second story of your house. If they are healthy and ready to go they will fly away.
If an adult ends up on the ground or inside the fire box of a chimney on a flat surface, they are completely helpless and cannot take off in flight unless they are on the side of a structure. The simplest solution is to put them back up the chimney and close the damper.

FLICKERS AND WOODPECKERS
 
These birds also cling, not perch. A cage should be lined with a towel, so that the wire on the cage does not damage the tail feathers. It should also have lots of logs for them to peck around on. The same insectivore diet applies. They are aggressive birds and will attack their own kind unless they have been raised together, so tread cautiously when caging them with other birds.

HUMMINGBIRDS
 
Hummingbirds feed on nectar, small insects and small spiders. They have a very high metabolic rate and must eat 50 to 60 times a day. Injured or ill adults will need to keep it in a small aquarium or box to prevent them from escaping. Place a towel on the bottom, a small branch close to the bottom and a piece of screen on top of the container. They are little escape artists, so a birdcage should have very small mesh. Place a small tube feeder in the container at a height that is easy for the bird to reach. An eye dropper will suffice if the bird is immobile. You will need to feed often, every fifteen or twenty minutes, taking care not to let the bird become sticky from the solution.

Homemade Hummingbird Formula
 
1 tablespoon sugar
4 tablespoons distilled water
1/8 teaspoon Ensure or Nutracal (high calorie nutritional supplement)
1 drop avian vitamins
1/8 approx. freeze dried insects (tropical fish food)
Blend all together so that is will easily flow through a tube.

Don’t forget a small container of water placed in the bottom of its container (a small jar lid works well).

If you choose to purchase commercially made nectar, be sure to add the other ingredients to it. The nectar is only OK for birds in the wild that can supplement their diet naturally.

PIGEONS AND DOVES

Pigeons and Doves, or Columbids eat from their mother’s crop. The mother produces what is called crop milk. The young sticks it’s beak into the mother’s crop and feeds, so you will have to tube feed them when they are very small. Hold the bird with one hand, gently open the mouth with the other and insert an eye dropper or pipette into the right side of the mouth and into the crop. Fill the crop half way about every thirty minutes until you feel comfortable doing this, then you can fill the entire crop and extend the feedings to about three hours.

As the baby matures add less water and make little dough balls, dip them in water and insert it into the crop of the bird. Eventually, add seed in the bottom of the cage and gradually decrease the formula as the bird starts eating seed. REMEMBER: All seed eating birds must have grit to digest the seed. This can be purchased where ever you buy domestic bird seed.

SEED EATER’S DIET

Kaytee’s Exact Hand Feeding Formula, or equivalent brand; add an avian vitamin and mineral supplement. Mix fresh at least once a day and keep refrigerated.


PRECOCIAL BIRDS
 
These are birds that hatch covered with down and begin to peck around for food as soon as their down has dried. They generally build nests on the ground and are easy prey to predators, lawnmowers, and people who pick them up when they should not. Anyone who sees a fuzzy baby walking around on its own naturally assumes that it is lost or distressed, but it is not usually the case. It is more than likely pecking around for food with the mother and rest of its siblings not far away.

These birds include shorebirds, geese, quail and ducks to name a few. Baby ducks around local ponds usually end up being picked up by kids or well meaning adults and if taken from the mother, will need to be cared for until it can fend for itself, which usually means adulthood.

A mesh cage works well to prevent escape, and remember that they are very good climbers and will escape from anything without a top. Place a shallow dish of Kaytee baby bird formula mixed with water in the cage along with a shallow bowl of water and very small birdseed and grit. A good substitute for mother is a feather duster hung from the top of the cage which allows it to go under for safety. It will need to be kept warm which means either a heating pad on low with towels under the cage to keep it from getting too hot, or an incandescent lamp over the cage. They are messy eaters and the cage will need to be cleaned often. These instructions work well with all precocial birds although ducks are the most commonly found. Most other precocials do not take to captivity as readily ducks and care must be taken, as with all wildlife; to keep them as stress free as possible and that means quiet and away from noisy children. Shorebirds and quail should be released into their own environment as soon as they are large enough to survive without mother

HERONS, EGRETS, BITTERNS
 
These birds are found in wet, woodland areas, streams and swamps as well as coastal wetlands. They are at home in both salt and fresh water. They like to roost on tree limbs and stumps close to the water’s edge. Their diet consists mainly of small fish, but will also eat prawn, crickets, crawfish, grasshoppers, snakes, frogs, mice, snails, water bugs, earthworms, leeches, lizards- anything they find along the water’s edge. The parents regurgitate the food, but it is not predigested. If the baby bird is newly hatched when you get it in, it is much easier to mix a tube formula for a few days. A good formula is:

1 cup Science Diet Feline Growth, dry
1 hard boiled egg
1 teaspoon calcium phosphate powder
1 teaspoon vitamin and mineral powder (Superpreen or Vionate)
1/2 cup Purina Trout Chow
1/2 cup water


Mix to a consistency to tube feed and feed slowly, making sure you are well past the air hole.

After about a week, start feeding small fish such as minnows. If all you can find is bait fish, cut the head off, cut into small pieces, dip into a vitamin mineral powder, making sure it contains vitamin B1. Try placing the food in front of the bird and encourage it to pick it up and eat it on its own. If necessary, pick up the piece of fish with a pair of forceps or long tweezers and place it into the throat of the bird. They have the capacity to hold a large amount of fish, but the fish should not be too big or the bones will be too large to swallow. At some point they should start attacking the fish you throw at their feet as a beginning to their self feeding. At that point, place the fish in a shallow pan of water. Keep trying this method. Eventually they will get the idea. In hot weather, the fish and water should be changed often to avoid spoiling. Juvenile birds should be released at about eight weeks old, but be sure they are self feeding, have good flight skills and are waterproof before releasing them into an area where others of their own species are found.

Birds of Prey

I have not included a chapter in this book on Raptors, or Birds of Prey. That is because they are so specialized it is absolutely imperative to their survival that someone experienced care for any hawk or owl that you may find to be sick or injured. Your state’s wildlife agency or the local humane society should have names and numbers of wildlife rehabilitators or centers that specialize in birds of prey in your area. If there are injuries to the wings or legs, they must be treated by a veterinarian as soon as possible. If a wound or break goes too long, it cannot be treated and the bird cannot be returned to the wild. Diet is also very specialized, so as tempting as it may be, for the sake of the bird, turn it over to someone trained in the field. The same applies to them as to any other wildlife you come in contact with. Keep warm, dark, and quiet until it can be turned over to the proper person.
