Part of biology is the science of botany explaining how fragile Earth's Nature balance is. BSB Science biology education online: Earth's birds do a lot of good, but swallows and other birds are threatened by emissions, pesticides, violent weather - Bear Springs Blossom Nature Education shows the beauty of cliff swallows. Learn about life on earth + all its variations, work with us to keep earth beautiful, to protect Nature. Learn to understand Earth's environment: Work with us to keep many countries on Earth beautiful. Look at all the different grasses. Grasses help to reduce erosion. Erosion takes good soil away, less food can be grown and harvested. BSB members support education, but need upgraded conservation education to take action against erosion, non-native species to keep Nature beautiful + to secure our future, to have a better life!

Cliff Swallows

Petrochelidon pyrrhonota

Close to BSB Nature preserve: cliff swallows and their colony at a cliff at Medina River Texas, protected by Bear Springs Blossom nature conservation
Cliff Swallow nests - colony at Medina River, TX
Swallows are beautiful and important insect eaters!

Can you imagine 83 swallow species?
That's how many different swallows exist on Earth.
Scientists have put them in the family Hirundinidae
characterized by their aerial feeding.
Swallows eat while flying!
cliff swallow shape, the typical form or shape of a swallow in flight feeding, nesting of cliff swallows Swallows love to live in colonies.
Cliff swallows lay 3-6 eggs. Their nests are made of mud and look gourd-shaped. Often we can see several hundred or thousand in a single location. Birders counted 3700 nests in one colony!
The nests are lined inside with grass to hold the mud pallets together.
Three-thousand-seven hundred humans together would be a nice town..
With the swallows it is a well working town, very social. Cliff Swallows help each other when food is scarce. Swallows will inform their neighbors in the nesting colony where to find food. When a swallow finds an insect swarm, it gives a specific call that alerts other Cliff Swallows that food is available.

Now the parents see a huge number of nestlings:
Which one to feed?
The parents find their own young in the creche primarily by voice.
As in humans every young swallow has a different voice.
Additionally parents can identify their children by their variable juvenal plumages. There are very distinctive facial markings on every chick.

What does an adult cliff swallow look like:
It is small and long-winged
It has a small bill
Its wings are long and pointed
It has a dark throat
It has a square tail
Its rump is pale

Swallows live only during the summer months in the US. In winter you can find the North American swallows in South America, many in Argentina. It is a very long flight for such a small bird that only weighs about 6 ounces.
