Our bird watcher data, now has a bit more complexity to it.

We've got more birds in our data and we're keeping track of birds habitat,

size and conservation status.

Each bird has a family and a scientific name.

They usually have more than one color and come from all over the world.

We track the habitats they live in by country.

We're also tracking individual reports of people who have cited the birds and

each sighting has the time and place someone spotted the bird.

As we move through the next few videos, we'll be applying our new knowledge

on Linked to practice and help us learn more about our bird watching data.

Let's take a look at our improved bird class.

I'm going to close the console to make it a little bigger for us.

Okay, we've got common name instead of just name.

We've got properties for family, scientific name.

Instead of just color, we've got primary colors,

secondary color and a list of strings for tertiary colors.

It's got a length, width, weight and then we've got a string size,

it looks like it returns us a string based on the length property.

We've got a list of sightings, that are of type sighting.

And we've got a list of habitats that are of type place.

We'll take a look at those two later.

We've also got a conservation status which is a string,

it looks like this is our list of conservation statuses.

They also have a code.

We've got an override method for two strings, so it prints out the name.

Then it looks like there's a constructor here, we'll just ignore this for now.

Let's take a look at the sighting class first.Alright

sighting looks like a bird and a sighting date and

observer first name and last name and it also has a place of type place.

Let's take a look at place.

Place has a bunch of strings country, city, terrain type and climate.

Okay, let's take in the data and see what we can find out.
