CONSERVATION STATUS

Least Concern

The Brown Noddy has a small breeding range of 26,800 square kilometers on many islands but a very large range outside of breeding. It is found in most subtropical and tropical waters around the globe. The estimated global population of this bird species is 180,000-1,100,000 individuals, and the species is not believed to be experiencing population declines that would require addition to the IUCN Red List. Because of this, the conservation rating of the Brown Noddy is Least Concern.

INTERESTING FACTS

  • Chicks reach adult weight in 18 days. Most chicks outweigh parents in six weeks. They are capable of short flights before reaching full wing development, and will flee if alarmed.
  • The Brown Noddy is the largest member of the noddy family; they weigh twice as much as black noddies.
  • This species exhibits breeding-site fidelity to an extraordinary degree. Apparently a pair returns to exactly the same nest year after year.
  • A group of noddys are collectively known as an "affirmation", "niddle", and "sleepiness" of noddys.
