Analyze the mapping interface settings

The prompt asks us to use the Half-Earth Project map with specific settings: "Richness", "\(1\text{ km}^2\) resolution", and "Hummingbirds".
Using the Species Richness Mapping concept, a richness map displays the total number of different species found within a given area.

Determine species estimation capability

Using the Hummingbird Distribution concept, we evaluate Question 1.
Because the map displays species richness at a high resolution (\(1\text{ km}^2\)), clicking on or hovering over a specific location on the interactive globe allows a user to see the exact or estimated number of hummingbird species present in that grid cell. Therefore, yes, you can estimate the number of species in a particular place.

Identify global distribution patterns

For Question 2, we describe the global patterns of hummingbird species richness.
Hummingbirds (family Trochilidae) are native entirely to the Americas (the New World).
The highest species richness (the "hotspots") is concentrated in the Neotropics, particularly along the Andes mountain range in South America, Central America, and parts of North America (like Mexico).
In contrast, they are completely absent from the Old World (Europe, Asia, Africa, and Australia).

Question 1

Yes, by using the "Richness" map at \(1\text{ km}^2\) resolution, you can hover over or click on a specific location on the globe to see an estimate of the number of hummingbird species present in that particular area.

Question 2

When rotating the globe, the following key patterns are visible:

• Geographic Restriction: Hummingbirds are exclusively found in the Western Hemisphere (the Americas). There are zero species mapped across Europe, Asia, Africa, and Australia.
• Latitudinal Gradient: Species richness is highly concentrated in the tropical and subtropical regions, particularly along the Andes mountain range in South America, Central America, and equatorial rainforests.
• High-Altitude Diversity: Mountainous tropical regions show the highest density of species richness compared to flat, temperate, or high-latitude regions.
