How to compare two organisms
Choose two species and trace their closest shared group. Then compare a trait with the same definition on each side. Check the units, life stage and context before interpreting a measurement or range.
Missing data means that the collection lacks a sourced value. Where a characteristic does not apply to a lineage, the comparison labels it separately. Open the two profiles for context and follow their sources before drawing a conclusion.
Evidence from the profiles
Compare their characteristics
| Trait | Bald Eagle | African Baobab |
|---|---|---|
| Physical traits | Adults have a white head and tail contrasting with a brown body and a large yellow bill. Young birds are mottled and acquire the familiar adult pattern gradually. | Thick, fibrous bark surrounds a broad trunk. Each compound leaf has several leaflets radiating from a central point. |
| Habitat and range | Lakes, rivers, reservoirs and coasts provide food, while suitable large trees offer nesting and resting sites. | A terrestrial tree of tropical Africa, it is adapted to seasonally dry conditions and is also planted in gardens and settlements. |
| Diet and nutrition | Fish are important, but the bird also takes other animals and carrion. Food may be caught directly, found dead or taken from another bird. | Leaves produce sugars through photosynthesis. Water and mineral nutrients are taken up through the roots. |
| Behavior and activity | Powerful flight and keen vision help eagles locate food over broad areas. The same bird can alternate between hunting and scavenging. | Data unavailable |
| Reproduction and life cycle | Large stick nests are built and reused. Both adults participate in caring for the young. | Large, hanging white flowers develop into capsules containing seeds embedded in pale, powdery pulp. New trees can be grown from seed. |
| Geographic distribution | Native to North America. Seasonal movements vary with access to open water and dependable food. | Native to Africa and cultivated elsewhere. The accompanying photograph shows a planted specimen in Madagascar; that location should not be confused with the native range of every baobab species. |
| Ecological role | As a predator and scavenger, the bald eagle draws on several parts of aquatic and shoreline food webs. | Its flowers, fruit and extensive woody structure provide biological resources. The familiar name baobab also applies to other species, which should not be confused with this one. |
| Distinctive adaptations | Data unavailable | A substantial trunk and drought-resistant growth form help distinguish this tree from many humid-forest trees. |
