To investigate birds we used:•Binoculars•Nets•Bowls with water •Camera•Magnifying glass

What did we do with these What did we do with these materials?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 non-flying 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.

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 TripsField TripsWe went to the field two times.

And the second was in October. It was hotter because it was Spring.

The first was in July. It was very cold because it was

winter.

In the field, we were divided into 12 groups.

We had an area of experimentation were we evaluated arthropods and grass.

Arthropods recordsArthropods recordsThe 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, larvaeand mosquitoes.

Vegetation recordsVegetation 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.
