Each gull species has its own vocabulary of sounds, and they communicate things such as mating rituals, warning calls, and location of food sources. Young gulls have high pitched whining calls that together with their behavior cause parents to regurgitate food for them. Most warning calls are growling-like. Some calls are soft and others are loud and far reaching to warn away competitors. You may be watching and listening to several species of gulls, and each species may have sounds peculiar to its species (such as mate attraction calls).

It is hard to connect "smarts" intelligence with brain size differences in animals. In some cases it is possible to judge intelligence and brain size, like if we were to compare a frog brain and a cat brain. However, when you compare the brains of the same animal species you run into problems. So it is difficult to connect brain size and intelligence when you compare one cat with another cat or a human to another human.

Something for you to think about: Elephants have a much larger brain than humans. Are elephants smarter than us?

  • Microscopic: too small to be seen with an unaided eye.
  • Organism: a living thing that can be small like bacteria or large like an elephant.
  • Plankton: a group of free floating organisms living in water that includes many kinds of plants and animals... more
  • Realistic: to draw, paint, or sculpt an object in great detail so that it looks like the object.
  • Scale Bar: a line drawn and placed along side an object or on a map to indicate the true size of the object or area of the map.

Sometimes when we only look at a plant or animal we miss seeing some of their amazing parts and how they are constructed. The story of the Invisible Watery World shows that there are tiny living things that come in many shapes and sizes. In lakes, streams and oceans there are plankton. These are small and often microscopic organisms.

A Biologists Life in the Rainforest

The rainforest is filled with many wonderful plants and animals. Biologist Kate Ihle is learning about the life of the tiny, but colorful orchid bee. This jewel-like animal is unlike the honey bees you might know. They can be both social and solitary. In this video Dr. Biology talks with Dr. Ihle in her field laboratory located on the tiny Barro Colorado Island in the middle of the Panama Canal.
