On Bird Behavior
Below are 3 essays, the first (Bird Light
Document) one
having been sent to me by a contributor. It is well written, and
deals with many aspects of bird behavior that I think should be
learned by anyone dealing with birds.
The second (Imprinting) and third (Transference) essays were written by me. They are
verbose to say the least. But I wrote them for a purpose. In
dealing with so many people, I have become aware of certain
misconceptions about birds that seem to be common, and I wanted
to address them. In fact, the third essay isn't really about
birds, but about the emotional reactions we humans sometimes have
to wildlife.
I hope you will find all 3
essays to be of use to you.

The following document was sent
to me during the days when I was still piecing together the
information for the chick I was raising. It was written by a
person who herself was taking care of a sand piper at the time.
It is very well written, and rounds out my site, which deals more
with the physical needs of the birds. Anyone who is interested in
bird behavior would do well to read it, since it can provide a
basic understanding of the underlying psychology that birds
possess.
Bird Light Document
I wanted to add
some things based on my experience, which is only with young
fledged birds, not naked nestlings (though I have learned a lot
about all ages from raising doves and finches). One might think
that an older, less helpless baby bird would be easier to care
for than a nestling. In some ways, it is, since they don't need
the constant care and temperature is less of a problem. But in
another sense, fledglings are more of a problem because the older
they are, the more of a stress captivity is on them. And stress
all by itself can kill them.
That is why I
mentioned the sedating effect of darkness, which is probably less
important for nestlings (though nestlings are used to darkness in
their nests). With a fledgling, reducing stress and, also,
reading the signs the bird gives about whether it is more or less
stressed are critical to the bird's survival.
Here are ways to
reduce the stress on a fledgling or injured adult bird. The most
important thing of all is to pay attention to the signals the
bird is giving you.
1) To birds, light
is a stimulant and darkness is a sedative. If it is struggling or
acting stressed out, darkness can sedate it immediately. Even
when you just pick up a bird, covering its head to shut out light
will calm it down immediately. A bird that is acting stressed or
upset should be kept in a dark environment. When you are keeping
the bird, watch the bird for its responses. That will guide you
as to how much light its environment can have.
On the other hand,
a sick or torpid bird may need the stimulant
of light -- especially sunlight -- and as a bird becomes used to
its environment, sunlight can help to cheer it up and make it a
happy bird. Precocial birds (birds that start running around and
eating as soon as they are hatched, such as quail, pheasants,
killdeer, sandpipers, etc.) need bright full-spectrum light to
stimulate them to eat.
2) Too much
movement around it can also cause a bird stress. If it is in a
cage, and acting stressed, cover part of the cage, especially if
there is movement around in those directions. The bird will
generally be less stressed if all the movement it sees comes from
only one direction (which is the situation it usually had in its
nest).
3) Sound is a key
to relaxing a bird. I have had great results with CDs of bird
song. Birds sing only when they feel safe. They go silent when
there is danger. (Ever pass a bush full of cheeping sparrows?
Ever notice how that bush will go silent if the sparrows become
aware of your proximity?) Birds take their cue about whether an
environment is safe or not from other birds -- regardless of
species. This is the reason why they flock -- the sense of safety
in numbers and the sense that if other birds feel a place is
safe, it must be. It doesn't matter if the other birds belong to
a different species, since they are all watching out for more or
less the same dangers. That is why CDs of cheerfully singing
birds is a reassurance to an anxious captive bird that the
environment is basically safe.
If you have tame
pet birds, their "endorsement" is also a reassurance to
the anxious wild bird (though you should not allow them direct
contact because wild birds almost always carry parasites, and
occasionally carry diseases).
4) Related to
that, if you TALK to the bird as you feed it, especially in a
high voice, that will reassure the bird that you are not a
predator. Predators do not talk to birds. Predators are quiet and
sneaky. -- Talking (in a high voice) or whistling to wild birds
will also help them to feel at ease around you. It reassures them
that you are not a predator, and they will often respond by
trying to communicate with you. Birds do communicate across
species and, as different as we look from them, they can learn to
recognize humans as fellow beings who can be communicated with.
5) Learn to
recognize the feedback the bird is giving you. Here are good
signs:
a) Closing its
eyes, especially the inner eyelid or closing from the lower lid
upward, is a sign the bird relaxed and happy. However, they also
do it when they are sick (perhaps because of endorphins) so if
they keep their eyes mostly closed all the time, even when things
happen that should snap them out of their relaxed state, or if
they do not seem alert generally speaking, they might be sick.
b) Preening is a
sign that the bird is happy and doing well. Birds do not preen
unless they feel at ease and unless they are healthy. The same is
true of taking a bath. Basically, a bird that concerns itself
with grooming is a happy healthy bird.
c) Calmly cocking
its head and studying you or other things in its environment is a
generally good sign.
Signs of stress
can be obvious. If the bird is thrashing around and desperately
trying to get out, it is not a happy bird. If it sits passively,
it may have given up and be preparing to die. If it sits puffed
up, it is cold and may be sick.
If the bird
vocalizes, it could mean many different things. It is not always
easy to understand all of the nuances of bird vocalization, but,
as a general rule, one could say that it means what it sounds
like -- if the bird =sounds= relaxed or happy, it probably is; if
it =sounds= upset or distressed, it probably is; if it =sounds=
as though it is asking for something, it probably is.
Use the same
natural instinct that you have for interpreting the sounds made
by a human baby. Birds use sound for bonding. Calling back and
forth is a bonding activity (this also helps create friendships
and bonds with wild birds). If the bird makes a noise and you
have the impulse to imitate the noise back to the bird, follow
that impulse! A call that makes you feel like calling back is
=intended= that way by the bird. Calling back and forth is a way
of bonding among birds -- the same way that echoing baby talk to
a baby is a way of bonding.
As you work with
the bird, be alert to its cues, the feedback that it gives you.
Sheer stress can kill a bird, and, on the other hand, a happy
bird is a healthy bird.
---------------------------------------------------------------------------------
I would like to
add to this that for young song birds (with
few or no feathers), generally speaking you should keep their
area dim. Bright light seems to be very bothersome to them, so
much so that they will constantly roam to get away from it. As
stated though, take your cues from the bird, and see what makes
it happiest. In case you have trouble knowing what happy is for a
young song bird, they often just lie there resting, without
panting or shivering, with good regular breaths, and they respond
immediately once they realize you are there to feed them. Any
change in the above behaviors should be viewed with suspicion.

About
Imprinting
You've no doubt already heard
about imprinting, the phenomenon in which young birds, when kept
from a very early age, consider not only that their human
caretakers are their parents, but also come to consider
themselves human as well. This is a real phenomenon. However,
there is currently some debate about how deeply it can affect
birds, and whether it is truly irreversible or not.
Again, I'm not an expert on
this issue, but it seems that imprinting is more of a concern for
some groups of birds than others. Raptors, owls, ducks, geese,
and other generally "larger" birds seem most affected
by imprinting. From my own experience and those I have heard from
many other caretakers, it does not seem to be as much of an issue
for Passerines (songbirds). Despite the
familiarity that grows from the caretaker/nestling relationship,
songbirds seem to still realize that they are birds. Once
released, they immediately or eventually seek out their own kind,
and many behaviors, social and otherwise, seem instinctive,
though they may have to learn the finer points.
It is this last point that is
of most importance to us as caretakers. It is vital that hand
raised birds NOT be released too soon. The amount of time varies
depending on the species. (see 'Species Info.' for details). They must be given the
time to learn the skills they will need in the wild. And as
discussed on the 'Release'
page, you can help foster many of these behaviors yourself.
Another concern with handraised
birds is their acquired dependency on humans. While I see nothing
wrong with maintaining a relationship with a bird once it is
free, the dependency must be broken. The bird must be able to
learn to forage and find shelter elsewhere. In a worst case
scenario, if you had to leave your home for a couple of days, a
dependant bird could in theory starve to death. Just as likely,
he may consider other humans as possible sources for these, and
this could possibly be harmful in itself if the new person is
unable or unwilling to accede to an "attacking" birds
wishes. Be sure to provide any food, shelter, or even sometimes
comfort the bird absolutely needs at the start of his release,
but do not coddle him. He must learn that you won't always be
around for him.
An exception might be made for
the corvids (crows, jays). Because of their ability, and indeed
need, to learn, it is possible that they may be prone to
imprinting. My feeling is that they do not generally become
imprinted, but have a greater dependency than other birds on
their family, be they the natural parents or the adoptive human
caretaker. Check the 'Species Info.' page for strategies to deal with
these birds.
It is nonetheless a wise
precaution to limit the number of people who deal with young wild
birds. No more than 2 people should be allowed to care for the
bird and interact with it. While dealing with more people
probably won't cause imprinting, it will cause a false sense of
security that can become dangerous once the bird is free.
------------------
A
Final Note On Transference
Transference is the ability we
humans have of believing that others are emotionally feeling the
way we think they should be feeling, or how we believe we would
feel in their circumstances. This is a natural trait for all of
us, and even professionals occasionally fall into that thinking.
As a social species ourselves, this is a vital behavior for our
survival. It allows us to empathize with others, and provides
motivation for mutual co-operation. However, in our dealings with
other species such as birds, this can have both a positive and
negative effect. Of course when we see a nestling lying on the
sidewalk, baking in the hot summer sun, we naturally feel that he
is suffering, and we are right. But there are many other
behaviors that are often wrongly interpreted, either through lack
of education on the subject, or more frequently, through the over
powering stimulus of our own "hearts".
While these misguided feelings
are understandable, and even perceived as good character traits,
the consequences of acting on them can often be bad.
This is of course, a complex
psychological subject, and I don't want to delve into it anymore
detail than necessary. Suffice it to say that you must step back
from your feelings when raising a wild bird. They can be made to
serve you, but you must not allow them to control your actions
outright. Listen to them, and coldly evaluate whether they have
any real basis in fact. Then, if you truly believe that this
feeling should be acted upon, do so. But remember not to go over
board.
To more thoroughly explain what
I mean, I have listed several examples below of transference told
to me by visitors to my site.
1- Loneliness.
Many people expressed concern
last year about their birds feeling lonely at some point or
another. In most cases, my judgement was that the concerns were
not justified. From my own experience, it seems to me that naked
nestlings know no loneliness. What they do know is hunger and
discomfort. If a nestling is crying out while you are not there,
he is either hungry, or in pain. He is not calling out for your
attention or company. You'll notice that as you approach him,
he'll get louder and louder until you put some food into his
mouth. And when he has had his fill of food, he goes right off to
sleep again. That is the limit of their "emotional"
needs at this time.
At the fledgling stage, this
changes, and they do want your attention. This need for attention
still has a large "give me food" component, but by this
point, you will also have become a reassuring presence in the
life of this bird. Feel free to give the bird some attention, but
limit the amount of time you spend with him, say no more than
10-15 minutes at a time. Then leave, or at least ignore him. He
will certainly feel lonely at this stage when you are not
present, but it is a step that he must overcome.
For those of you that have
found a fledgling outdoors, and who wisely decide to leave it
outside but keep an eye on it to see if it is truly abandoned or
not, the last thing you need to worry about is whether they feel
lonely or not. They may or may not feel lonely, depending on the
species. Young robins are typically left alone (separately) by
the parents for quite some time during the day when they have
first fledged, and are left completely alone during the night.
These birds simply remain still, waiting for the return of their
parents, whenever that may be. New-fledged blue jays on the other
hand, are occasionally left alone with their siblings while the
parents forage, and these need each other's company. Within a few
days, their flying endurance is strong enough that they will
follow the parents everywhere. A lone fledgling blue jay is
indeed lonely. But even here, that is not the main concern. The
real concern is have the parents truly abandoned it? Or is it
injured or sick? Only if you are sure of that one of these
possibilities is the case should you intervene.
The philosophy in the preceding
paragraph applies equally well to just-released birds. For
handraised birds, I have no qualms about occasionally yielding to
the urge to comfort your bird, especially during the first few
days after release. But your job at this point is to promote
independence, and that's going to mean a little tough love.
2- In keeping with the above
topic, the love issue.
This has always been a
emotional subject. From my observations, I believe birds can love
to a degree. But I think many people take the
idea too far, and expect that birds have the same emotional needs
that we do. Accept whatever fondness a bird seems to display for
you, but don't imagine it to be a major driving force in his
life. It is what it is, and it won't last as long as many people
seem to think.
3- He desperately wants his
freedom!
Here we hit a great bone of
contention between the purists (he'll only be happy if you let
him go) and those whose hearts command them. (he'll be so sad
being on his own) Both examples can be considered as
transference.
Like everybody else, I have my
own opinions on the matter, and I'm going to go out on a limb by
stating them. I do not believe that a wild bird is necessarily
happier than a kept bird. The wild life is a hard one, with many
daily problems and dangers. On the other hand, I also believe
that many pet birds are also unhappy. I find that in many cases,
they are not given the freedom (as it were) and diversion that is
necessary to them. It comes down to what the bird is used to, and
what needs he has.
Understand that despite my
opinion on the matter, I do not condone keeping wild birds as
pets. There are many other issues to consider than just their
happiness. Legal issues, health and welfare not only of the bird,
but of ourselves, and even the species in general, must be
considered. We have to look at the bigger picture to see that it
is all around a better thing to release the bird than to keep it.
But we mustn't get too carried away by that either, which could
lead to errors in judgement as to when to actually release the
bird.
So now, you'll hopefully have
an idea about what transference is, and how you should deal with
it. By trying to always put the birds needs above all, you'll be
helping to make him a stronger member of the outdoor community.
