Nest by the pond in the park (terms)
Terms
- drupe
- A fleshy fruit in which an outer layer surrounds a hard stone that encloses a single seed.The fruits of Celtis australis are small drupes that ripen in autumn, eaten by birds and dispersed across the city.
- fledgling
- A young bird that has recently acquired its feathers and is learning to fly and survive outside the nest.Rock pigeons nesting in Celtis australis produce fledglings that take their first short flights from the shelter of the tree’s branches.
- mutualism
- A type of symbiotic relationship in which both species involved gain benefits from their interaction.When pigeons eat and disperse the fruits of Celtis australis, the birds gain food while the tree benefits from seed dispersal, illustrating mutualism.
