Questions

migratory?

Materials and Methods
Previous Records
(May 2010 - October 2010)
•
Maximum and minimum temperatures
•
Sunlight: sunrise and sunset records
Materials
To investigate birds we used:
•Binoculars
•Nets
•Bowls with water
•Camera
•Magnifying glass
What did we do with these
materials?


Binoculars: we used them to see birds a bit
closer when they were far away.
Nets: they were useful to catch the flying
insects that were in the grass.
Bowls with water: we used them to trap nonflying insects (the food of some birds).
Camera: we used it to take pictures of birds and
identify them.
Magnifying glass: it was necessary to have a
better view of insects caught in the bowls with
water.
Which are the methods?

We made a photographic safari. A
photographic safari is when you take
a lot of pictures from the same
thing. We entered the page
www.flickr.com to see some pictures
of migratory birds and to upload our
pictures. The objective of the
activity was to know more about the
birds that appear in the area.
Field Trips
We went to the field two times.
The first was in July. It was
very cold because it was
winter.
And the second was in October.
It was hotter because it was
Spring.
Our Field


In the field, we were divided into 12 groups.
We had an area of experimentation were we
evaluated arthropods and grass.
Bird records

The teachers gave each group a
field sheet were we had to write the
information we collected when
observing birds, like what they eat,
what they do. We also had to write
what species of birds we could see
at that moment and their activities.

Arthropods records
The grass was very tall in the area of
investigation
because
we
had to
investigate the insects that were on it.
We put some recipients full of water and
we used nets to catch some insects and
observe them trough a microscope. We
used magnifying glass to look at the
insects more clearly.
We found: Woodlice (bug ball),
spiders, wasps, larvae
and mosquitoes.

Vegetation records
We observed the grass in the area of
experimentation to collect information
about the fruits, flowers and insects that
appeared there because they are the
food of the birds.
 We also observed trees and completed
the field sheets with the same
information.
 We collected samples of fruits, seeds,
and leaves to investigate them.

In October birds were more active because
there was more food and because of the
early exit of the sun.

Conclusions
During the spring there were more
birds and they were more active
because there was more food for
them: there were more arthropods,
flowers and fruits.
In winter the birds were more
worried
about
food,
probably
because there was less to eat.
