How ring-necked parakeets choose a nesting site.
Ring-necked parakeets are hole-nesters, often taking over an old woodpecker nest hole, or a larger-sized nestbox. They start nesting early, often in January, but some birds lay eggs as late as June.
The early start to the breeding season means that they have a wide choice of nesting sites with little competition for holes. Their main competitors are starlings, and also woodpeckers and owls.
The female lays 2-4 eggs, and incubates them for three weeks. The young are cared for by both parents, and fledge when they are 40-50 days old. Their nesting success is very high. They normally mature to breed when they are three years old.
