  • A chemical engineer in Melbourne, Australia, meticulously documented bird species in Birrarrung Park for 40 years.
  • His extensive records, comprising over 800 visits and 153 species, offer valuable scientific insights into environmental changes.
  • These citizen science observations are crucial for understanding animal population shifts due to climate change and habitat loss.

For four decades, Mike Connor, a retired chemical engineer, has been a dedicated observer of Birrarrung Park in Melbourne, Australia. His commitment began in 1985, the same year Uluru was returned to its traditional owners and Paul Keating warned of Australia becoming a "banana republic." Connor, then 41, started visiting the park, initially unimpressed by its appearance as "just old farmland."

I've always just kept a list of what I've seen and what I've done.

— Mike ConnorExplaining his habit of documenting his park visits.

Driven by a lifelong love for birdwatching, stemming from a childhood spent indoors in England observing birds outside his window during bouts of bronchitis, Connor began keeping lists of his sightings. These weren't just casual notes; they became a detailed chronicle of the park's avian inhabitants. Over 40 years and more than 800 visits, he recorded an astonishing 153 species of birds.

The park wasn't a particularly attractive environment, it was just old farmland.

— Mike ConnorDescribing his initial impression of Birrarrung Park.

Connor's sustained observations have proven invaluable to ecologists like Emeritus Professor Andrew Bennett. Such long-term, consistent data from a single observer is rare and provides critical insights into environmental dynamics. Connor witnessed firsthand the slow return of vegetation after droughts, the transformation of wetlands during floods, and the emergence of a forest from revegetated farmland along the Yarra River. His records reveal how bird populations shifted, with some species declining, new ones appearing, and others fluctuating with changing conditions.

What is extraordinary in this situation is having observations by the same person, not a series of different observers, in the same park, for such an extended period.

— Emeritus Professor Andrew BennettHighlighting the rarity and value of Connor's long-term data.

"What is extraordinary in this situation is having observations by the same person... in the same park, for such an extended period," Bennett stated. "In my experience, I've not previously come across such a sustained duration of regular observations." Together, Connor and Bennett analyzed these records, recently publishing their findings. They emphasize the high conservation value of urban parks like Birrarrung and the significant scientific contributions citizen scientists can make, offering insights that might otherwise be missed.

In my experience, I've not previously come across such a sustained duration of regular observations.

— Emeritus Professor Andrew BennettEmphasizing the unique nature of Connor's commitment.
