Hand Taming Wild Birds – Attracting and Feeding Wild Birds
Dec 31st
Hello, Frank Indiviglio here.
Now that bird-feeding season is upon us, I’d like to pass along some thoughts on one of the most pleasurable aspects of this hobby, the hand-feeding of wild birds. Strange as this may sound, it is actually quite simple to train a number of species to feed from the hand – assuming, that is, that you have patience and the ability to remain still in cold weather!
I was first made aware of the prospect of hand-feeding by a wonderful little book given me by my grandfather, who was always looking for new ways to see animals up close: Hand Taming Wild Birds at the Feeder (Martin, A.G., 1963; Bond Wheelwright Co.: Freeport). Over the years, I have found that chickadees, juncos and cardinals to be by far the boldest of the typical “backyard birds”. However the occasional hairy woodpecker, nuthatch or catbird may surprise you with a visit, and the aforementioned book’s author has had success with an incredible range of species.
Keeping your Guests Calm
An important point raised by the author is that you not stare directly at a bird which alights on your hand. This is good advice, and was borne out in my later experiences working with birds in zoos. If you want birds to stay close so that you can observe them, don’t stare…they will allow a much closer approach if you use sidewise glances, at least at first. Birds recognize eyes, and associate a stare with danger, it seems.
An Interesting Twist – an Owl that Fed People
I found it interesting that birds also seem to “know” what a mouth is. The author makes the point that one ought not “swallow” when a bird is on the hand, lest it fly off. A screech owl that I once helped to raise definitely confirmed this. He was imprinted on people and when ready to breed attempted to offer mice (a traditional owl nuptial gift) to his human friends. Alighting on a shoulder, he would invariably attempt to jam the mouse in one’s mouth – never in an ear!
The Best Foods to Use
When feeding wild birds, choose a seed mix that contains a wide variety of ingredients (i.e. Scott’s Multi-Bird Blend), so as to attract many species. A good hand-feeding technique is to offer pieces of suet. Although often thought of as being specifically for woodpeckers, birds of all kinds crave this high-energy food in winter…its presence in your hand will help to overcome their initial shyness.

I’ll add bird-feeding notes from time to time. Please send in your own ideas and questions as well. Thanks, until next time, Frank Indiviglio.

Dec 29th
Hello, Frank Indiviglio here.
Please see: Two Mid-Sized Parrot Clowns: the Black-Capped and White Headed Caique, Pionites melanocephala and P. leucogaster, Part 1, for general information on caique care.
Black-Capped Caique, Pionites melanocephala
Description
The caiques are unique among South American parrots in displaying a white breast. This is set off, in this species, by the bright green wings and back and a black face and crown. The abdomen, thighs and under-tail are yellowish-orange.
Subspecies
Two subspecies have been described. The nominate form, P. melanocephala melanocephala, is found in the eastern and southern portions of the range.
In P. melanocephala pallida, sometimes referred to as the pallid caique, the abdomen, thighs and under-tail are yellow instead of orange. Intergrades, showing characteristics of both subspecies, are common where the ranges overlap. The black-capped caique also interbreeds with the white-breasted caique (please see below), further confusing identification of the various subspecies.
Range and Habitat
The range extends from eastern Venezuela to French Guiana and south through southwestern Columbia and Ecuador to northeastern Peru and northern Brazil.
The black-capped caique is most commonly encountered along forest edges near rivers, swamps and other bodies of water. It generally forages in the canopy, but will venture into adjoining savannas to feed as well.
Behavior and Social Groups
Caiques may be seen in pairs, family groups or small flocks – but whatever the arrangement, there is always a good deal of noise. Observers often note that caique flocks always seem to be larger than they actually are, due to the racket they create. As in captivity, they are always in motion.
Black-capped caiques have been observed to engage in a behavior that has come to be known as “crowing”. A bird, apparently of either sex, will perch and raise its wings high over its head, exposing the bright orange under-feathers in the process. While so poised it emits a “piping call” that has not been heard at other times. “Crowing” is believed to be a contact behavior.
Black-Capped Caiques as Pets
Black-capped caiques are more commonly kept than are white-breasted caiques. They are quite active, rolling about and playing – with each other and favored people – in a most endearing manner. Although not known for their speaking ability, in time they can amass a decent repertoire of words. Caiques are best acquired as young, preferably hand-raised birds, as they have a tendency to use their strong beaks when trying to “make a point”. Please see Part I of this article for further information on captive care.
White-Breasted Caique, Pionites leucogaster
Range and Habitat
The white breasted caique has a more limited range than its black-capped cousin, and is less commonly seen in captivity as well. Three subspecies occur through eastern Peru, northern Bolivia and northern Brazil. It is native to eastern Ecuador as well, but its continued presence there is now uncertain.
Like the black-capped caique, this species usually moves about and feeds high in the treetops, and frequents forests bordering watercourses.
Description
The three subspecies differ a bit in color. All share a white breast. The nominate race, P. leucogaster leucogaster has green thighs while those of the other subspecies are yellow.
The yellow-tailed caique, P. l. xanthurus is limited in distribution to northwestern Brazil and has, as might be expected, a yellow tail along with yellow thighs. Its overall color is somewhat paler than that of the nominate race of the other subspecies (the yellow-thighed caique, P. l. xanthomeria).
Naturally-Occurring Hybrids
The yellow-thighed caique and the black-capped caique overlap throughout parts of their ranges, and frequently hybridize in the wild, leading some ornithologists to question the validity of their taxonomy.
Both caique species, as well as hybrids, are bred in zoos and private aviculture. I’ll cover reproduction in a future article. Until then, please write in with your questions and comments. Thanks, Frank Indiviglio.

Dec 26th
Hello, Frank Indiviglio here.
_-Nelson_Bay_-NSW.jpg "Rainbow Lorikeet")
The 56 lory and lorikeet species are among the most gorgeous and active of all parrots, and are usually quite bold in character. In both the wild (particularly Australia) and in zoos, lory feeding stations are a great hit with tourists, with hundreds of colorful birds flocking onto treat-bearing visitors.
The Effect of Feeding Ecology
Lory and lorikeets rely primarily upon a relatively scarce, widely-scattered food source – pollen and nectar, and herein lays the explanation for their aggressive feeding behavior. Competition at feeding sites has fostered in these birds a repertoire of over 30 threat displays…a far greater number than is seen in other parrots. Unfortunately, these tendencies often express themselves as aggressive behaviors in captivity, with even long-paired birds sometimes running into difficulties.
Space and Aggression
A change in the environment is frequently a pre-cursor to aggression. Giving the birds more room – a great concept in principal – often leads to fighting. This is true for many birds (and other animals)…I once lost 2 white-crested laughing jay thrushes to aggression after giving birds that had lived peaceably together for 18 month access to an adjoining cage. Of course, crowding can also lead to fights, but the possibility of extending or establishing a territory seems an especially strong factor. Lories seem particularly prone to this phenomenon.
Adding a Nest Box
The provision of a nest box may bring on breeding-related aggression in an otherwise peaceful male, and moving even a long-established pair to a new cage is always a cause for concern. Be sure to observe your birds carefully at such times, and separate them if you will be away for long periods when the change is first instituted.
Introducing Birds
Introduce new birds by caging them side-by-side, and confine a possibly troublesome individual to a small cage or carrier within the larger cage, if space permits, to allow the birds to get used to each other. I relied upon this method with a wide variety of birds in zoo situations, and found it most useful. If using a carrier for the introduction, choose one with barred as opposed to solid sides, so that the birds can interact. Pets International Take Me Home Traveler is ideal.
Other Considerations
Limiting mobility by clipping the wings of aggressive birds is another tried and proven method of easing the introduction process. The availability of a wide variety of bird toys and a complex, well-perched cage will go a long way in keeping your birds occupied with constructive (rather than destructive!) activities. Of course, proper lory nutrition is essential in fostering normal behavior and good relations among your pets.
Thanks, until next time, Frank Indiviglio.

Dec 22nd
Hello, Frank Indiviglio here.
Have you ever wondered why, in most bird species, the male with the loudest song, brightest plumage or most spectacular display is usually successful in attracting a mate? Given that birds have so many predators, and that the efforts of both parents are usually required to raise the chicks, it always seemed to me that females “should” prize males who went about their lives quietly and unobtrusively. Wouldn’t these be less likely to attract a predator’s attention than those strutting about and singing for the entire world to see?
In no species is this phenomenon more clearly illustrated than the Indian peafowl, Pavo cristatus. The above-mentioned thoughts came to be with great force while I as contemplating the American Museum of Natural History’s spectacular Asiatic leopard display. The exhibit features a leopard that has just captured a male peafowl, and the panoramic background painting depicts other peafowl flying off. Viewing the scene, one can easily imagine how a huge, colorful train of feathers might hinder the peafowl in escaping predators. Why then, does it assist the male in his efforts to secure a mate?
The answer is apparently to be found below the surface of what we see. By displaying large adornments and reckless behavior (i.e. singing from an exposed perch), the male bird is, in essence, proclaiming his ability to survive despite such encumbrances. He must, therefore, have sprung from fine genetic stock, and is perceived as being able to sire strong, healthy offspring. The very act of growing such adornments or developing a strong voice also indicates his good health, and the ability to procure a generous amount of food.
Of course, here there arises a great temptation to make comparisons to human behavior, but I’ll leave such for my readers who are better versed in that subject than I!
Peafowl are extremely interesting captives, and very popular in private aviculture. I enjoyed caring for a large group that ranged freely over the grounds of the Bronx Zoo – more on that soon. Until then, please write in with your questions and comments. Thanks, until next time, Frank Indiviglio.
