Goldfinches build their nests in relatively open areas, often in shrubs or small trees 3-10 feet above the ground. The nests are typically located at the end of branches, hidden by foliage from above but often visible from below
This location provides some protection from ground predators while still allowing the parents easy access to the nest.
The female goldfinch constructs a tightly woven, cup-shaped nest out of plant fibers, spider silk, and down from seeds like milkweed and thistle
The nest is so well-made that it can actually hold water. This sturdy construction helps prevent eggs and nestlings from falling out, even in windy conditions.
Goldfinches often nest in small, loose colonies, with several pairs nesting in close proximity
This communal nesting may provide some protection from predators, as more eyes and calls can help detect threats. The close proximity of nests also allows parents to more easily defend against intruders.
If a predator approaches the nest, both male and female goldfinches will aggressively mob and harass the intruder, often diving at it and making loud alarm calls
