Historic Sighting: Siberian peregrine Falcon Spotted Deep in Australian Outback
Table of Contents
A rare Siberian peregrine falcon has been documented in central Australia for the first time, a remarkable event potentially linked to unusually heavy rainfall. The sighting, confirmed by the Australian Wildlife Conservancy (AWC) on Tuesday, February 3, offers a compelling glimpse into how changing climate patterns might potentially be influencing wildlife distribution.
Unprecedented Inland Sighting
the bird of prey was spotted in February 2025 by AWC wildlife ecologist Tim Henderson above the Newhaven Wildlife Sanctuary,near Alice Springs. After careful analysis of photographic evidence, experts definitively identified the falcon as a Siberian peregrine falcon (Falco peregrinus calidus), a subspecies typically breeding in the Arctic tundra of Eurasia.This represents the farthest inland this subspecies has ever been recorded in Australia.
“I’m honestly amazed that the image didn’t come out blurry,” Henderson saeid in a statement. “The bird was moving far too quickly to identify in the field, but it looked different to the usual peregrine falcons we see in Australia and I’ve made a habit of snapping photos to review later.Especially with peregrines, there’s always that chance a rare subspecies might appear – as was the case here!”
Rainfall and Raptor Diversity
The appearance of this long-distance migrant is believed to be connected to remarkable rainfall across Australia in 2024. The national average of 596 millimeters (23 inches) was 28% above the 1961-1990 average, making it the eighth-wettest year as records began in 1900, according to the government’s Bureau of Meteorology. the Northern Territory, where the Newhaven Wildlife Sanctuary is located, experienced its fourth-wettest year on record.
Specifically, the sanctuary received 316 mm (12 inches) of rain in March 2024 alone, totaling 637 mm (25 inches) for the entire year. This surge in precipitation, described as “the most we’ve had in a year as 2001, and the 5th wettest year on record,” created temporary wetlands and water sources. These conditions attracted large numbers of prey species, subsequently drawing in a diverse range of raptors, including the Siberian peregrine falcon, the goshawk, and others.
A Global Traveler in Unexpected Territory
The peregrine falcon (Falco peregrinus) is renowned as the world’s fastest animal, capable of reaching speeds exceeding 199 mph (320 km/h) during dives. While found globally – excluding Antarctica – these birds are known for their long-distance migrations. The Siberian subspecies typically travels south following the Northern Hemisphere summer, but is considered a “rare migrant or vagrant” to australia.
Sightings of the Siberian subspecies are most common along the coastlines of northern and eastern australia, generating excitement within local birding communities. Henderson noted that up to a dozen sightings are reported annually through social media and online bird observation databases. However, these sightings become increasingly infrequent further inland, potentially due to lower population densities of birdwatchers.
A recent study, published in the journal Pacific Conservation Biology and authored by Henderson and colleagues, details the impacts of the 2024 rainfall on the local ecosystem and documents the falcon sighting.

The sighting underscores the potential for climate change to alter established migratory patterns and introduce unexpected species into new environments, highlighting the interconnectedness of global ecosystems.
