General
Care For Nestlings
So you may have to
raise the bird yourself. Read this page to learn how to meet the
bird's environmental needs, and what to expect as he grows.
------------------------------------------------------
1- Housing
- Find a cardboard
box with dimensions of about 1' long x 1 1/2' wide x 1 1/2' high.
- Place a heating
pad on the bottom of the box, turned onto its lowest setting.
- On this, place a
small bowl or smaller box, that is high enough to prevent him
crawling over the edge and falling onto the heating pad. The bird
will overheat if this happens.
- Inside the bowl,
place a folded towel, taking care to insure that the complete
bottom of the bowl is covered. The bottom of the bowl, even if it
is 'soft' plastic, is too hard for the little guy, as I found out
when I let mine sleep without a towel one night, and in the
morning he was miserable and had a very sore leg, which I'm sure
would have gotten worse if I did not immediately return his
towel. A small slightly upheld rag loosely placed on one end of
the bowl can be useful in allowing the bird to choose for himself
whether he prefers to remain under it, where the temperature is
quite a bit warmer, or to remain outside of it, to be cooler.
Make sure he has the option of leaving the fold easily.
- Put a
thermometer directly on the area where he will be living, and
check the temperature often. A good thick glass thermometer from
the pet store will do, but not one of those thin plastic ones
that can break too easily. You want to keep the temperature at
about 90 degrees. This seems to be the temperature that my
sparrow was happiest with, although it was recommended to me that
85-95 was acceptable. I tend to disagree. 95 seemed to hot for
him, and 85 not warm enough. Other species may prefer slightly
higher or lower temperature. In any case if your bird is panting
he is too hot. Other signs of being over-heated are if the bird
constantly keeps his mouth open, or seems uncomfortable and
restless, which can also be a sign of disease as well. These
signs can show up alone or in combination. If he is shivering,
act QUICKLY to raise the temperature!
- Adjust the
temperature gradually until you are sure he is comfortable.
- Keep a dark
towel on top of the box, with just enough of an opening to let a
little bit of air in. 1" or so should do, but this affects
the temperature in the box, so check it and compensate as
necessary. If the temperature goes a little too high, you can
also try putting a folded towel between the bowl the bird is
resting in and the heating pad. It will take a few hours to make
sure the temperature is stable, so keep checking.
- Keep the bird's
area dim, especially for cavity nesters.
- DO NOT use
grass, hay, straw, etc., as bedding. These can cause cause
illness and death.
- Do not use an
aquarium as a nesting box. Even with only a screen or towel on
top, the air circulation is too poor. Humidity remains high, and
can lead to bacterial contamination of the tank, or infection of
the bird.
A contributor
suggested the following alternative setup: A closed cardboard box
with about five air holes no bigger than a pen's circumference.
The heating pad was kept under the box as opposed to inside it,
and was set to 'medium'. If this setup successfully keeps a good
temperature range, then it would be the better bet since it would
protect the bird from drafts. In any case, the temperature should
be verified often!
Other methods of
assuring warmth can be used, but with caution. Light bulbs are an
easy source of warmth, but they will cause burns if allowed to
shine directly on the bird. They also dry the surrounding air to
unacceptable levels, which can be dangerous to the chicks in
several ways. The glare can also prove deleterious to young
birds. The light is too bright during the day, and at night, they
will need darkness to get their rest, but turning off the light
means no source of warmth. If using a light bulb, leave a blanket
or other barrier between it and the bird. A good idea could be to
use 2 boxes, one on top of the other. The light bulb could be
used inside the lower box, and the chick left in the upper one.
Then you could adjust the distance between the 2 until you reach
a good temperature around the bird.
Some people have
mentioned using hot water bottles to keep their birds warm. I
can't really recommend their use. The heat produced by the
bottles is not constant enough, and you will need to refill them
every few hours, including at night. They can however be used as
an emergency source of warmth, if nothing else is handy at the
time. Best to wrap the bottle in a towel before placing near the
bird. This will allow the heat to diffuse slower and more stable.
Take care not to over-warm the bird, and be sure that the bottle
does not leak, which could burn him if the water is still hot, or
chill him if the water has cooled down. (Both are deadly.)
About
"naturally" warm places around the house, such as tops
of the fridge, hot water heater closets, near radiators, etc. I
tend not to recommend these places since so many variables can
affect the health of the chick. But occasionally, a person does
seem to have a suitable place available in their home. Be very
careful using such a place. I would only recommend using such a
place if you truly cannot get a more suitable environment for the
bird. The factors to keep an eye on are: temperature, humidity,
fumes, cleanliness of the area, and available lighting. All these
preceding factors must be within the acceptable ranges, and
remain stable throughout the bird's stay in the area. Other
general safety issues must also be considered.
2- Growth
Growth should be
noted every day. The best thing to do is to weigh the bird each
day to insure that he is gaining weight. I had no device for this
myself, so I cannot be more detailed than that. But you should
notice things like bigger feet, eye development, color changes,
feather growth, etc. Sometimes you will only notice one thing,
such as when I noticed my bird all of a sudden had these huge
feet! He looked otherwise the same to me as the day before. This
is apparently normal. As long as something is growing, the bird
is doing alright.
3- Energy Level
The bird should
also have a good energy level when offering him food, and should
want to eat. If you notice a drop in these, start paying close
attention to him. He may have simply had a bad night, but more
likely he may be getting sick. If this behavior lasts more than 2
hours, raise the temperature to 95 degrees, and call a vet,
rehabilitator, or wait until the situation passes, one way or the
other. Try to observe his surrounding conditions for anything
noteworthy, like drafts, noise, fumes, etc.
4- Sleep
Let the bird get 8
hours uninterrupted sleep. Remember, he is a baby after all. Stay
out of his room, and keep all the lights off. However, on the
first couple of nights, don't let this stop you from checking the
temperature of his box. Simply bring a flashlight with you, and
avoid shinning it directly in the box. Take the thermometer out,
and read it there, then put it back.
5- Cleaning
Keep his area
clean. I removed my bird's droppings whenever I noticed them, and
I changed his bedding every 2 days, since we got a lot of food
all over his little towel.
6- Other
Animals
Do not let any
other animals near the chick. Even if the animal is friendly, you
do not want your bird getting used to that animal since when you
release him, you will decrease his chances of survival. Just
imagine that your bird has been playing with a friendly cat, and
then when you release him he goes to the first cat he sees
thinking it is a friend. There goes all your work! I would even
go so far as to say that you should not let the bird see you with
your animals.
It should also be
understood that under no circumstances should a wild bird ever be
allowed to near an indoor pet bird. They should not even be
present in the same room. The risk of disease transmission is
high, and pet birds generally do not have a strong immunity to
native avian diseases. If you own a pet bird, wash your hands
before and after dealing with the wild bird to prevent spreading
any illness. (You should be washing your hands anyway, for your
own sake.)
7- Toxic
Substances
No smoking, or
spraying of air fresheners, pesticides, cleansers etc., in the
bird's room. Keep all chemicals and toxins well away from the
bird. It does not take much to make the bird ill (or dead) with
these substances.
8- Pin Feathers
Growth rates can
vary from species to species, but usually it takes somewhere
between 2 to 4 weeks until a chick fledges. By the second week,
my sparrow only had pin feathers coming out of his wings and
tail, and they were not very long at all, maybe 1/4", if
that. By the third week, he had almost all his feathers, except
at the area on his body below the wings, a small patch on his
belly, and his leg feathers were only just coming in. On top of
that, most of his sheaths came off so that his feathers are
completely open and useable.
When feathers are
growing, you must be very careful not to break them, since the
birds can bleed to death. At this stage, the bird may seem quite
uncomfortable with the feathers coming out, which I suppose is to
be expected.
9- Safety
You will notice
that as the bird continues to grow, he will start becoming more
curious about his surroundings. He will start to walk, talk, and
flex his muscles. Young birds are usually pretty clumsy at first,
but in a few days they learn the ropes. Take care that your bird
cannot become injured with his little explorations, or fall out
onto the heating pad.
10- Fledging
Within a couple of
weeks to a month, the bird will have fledged, which means not
only does it have almost all its feathers, but it will actually
fly, or try to. They usually fly pretty weakly at first, but
within a week, they should have basically mastered it. I often
held my sparrow on my finger and let my hand down repeatedly to
get him to exercise his wings.
