TravelGuides – The whale sentinel: two decades of watching humpback numbers boom | Whales

He might have seen it tens of hundreds of occasions earlier than however when Wayne Reynolds spots a whale rising from the water, he reacts with the joy of a baby mentioning a rollercoaster at an amusement park.

“Oh wow, there’s a minke and her calf,” he yells out with boyish enthusiasm from the rocky cliff at Potter Point in Kurnell, in Sydney’s south. “I just go into auto-mode, I can’t help it.”

It’s a chilly Wednesday morning, the solar has solely simply made an look, and with the wind chill, temperatures are within the low single digits.

Reynolds is carrying a navy camouflage-patterned hoodie and pants, and a large grin.

Humpback whales tail-slap in the ocean off Potter Point in the Kamay Botany Bay national park near Kurnell at first light.

Without gloves, his palms are gripping his binoculars, as he stands searching into the Pacific ocean.

“Humpback! Humpback over there, he’s just put his tail up,” Reynolds shouts. The humpback is one of a number of species he is ready to recognise by the pores and skin sample on its tail – a talent he has developed in additional than 20 years as a citizen scientist observing the mammals.

This whale is swimming so near the coast that its measurement is confronting – Reynolds estimates it’s about 15m lengthy, and should weigh about 40 tonnes.

“That’s a big girl, that one. The girls are bigger than the males,” he says, as she slaps her tail repeatedly.

“That could be a communication with other whales, or just slapping off barnacles. Or there could be something annoying her,” Reynolds says.

Heavy fog makes some of the whales tough to identify that morning, however Reynolds’ skilled eyes can detect their presence from a vortex of water generated by the motion of their tails, which he says “creates a circle like an oil slick” on the floor.

It’s a number of weeks into Sydney’s watching season, when whales migrate from the Antarctic to hotter waters off the Great Barrier Reef to feed and breed by the winter.

‘There’s an superior energy’

Surrendering most of the daytime throughout these months to watching whales is nothing new for Reynolds, however the place he watches them from has modified.

Potter Point is on the south finish of Botany Bay nationwide park, a brief vantage level the place Reynolds and fellow volunteer whale watchers have arrange whereas a whale-watching platform is constructed at their conventional base at Cape Solander, on the reverse finish of the park, the place they started watching from a carpark decades in the past.

Having retired as a diesel mechanic on the age of 27 in 1992 after being identified with power lung illness, Reynolds was dealing with a future “sitting at home bored shitless” on a incapacity pension.

He noticed a newspaper advert to volunteer for WIRES wildlife rescue, and after being concerned in some whale rescues, and seeing the mammals up shut whereas jet snowboarding off Cronulla, he turned fascinated.

“You’re witnessing one of the biggest living animals in the world. There’s an awesome power of the whale, I can’t really explain what else keeps me coming back.”

In 1996, Reynolds started watching whales usually from Cape Solander, and a yr later led a pilot program in coordination with the nationwide park to file observations in a critical method for the period of the migration.

The research formally launched the next yr, and has attracted untrained citizen scientists, in addition to volunteer marine researchers and the rescue group ORRCA, because the whale watching motion grew.

In the 24 years since, research volunteers have monitored whales from 6.45am till 4.45pm for the period of the season.

In the early years, the group sought to maintain requirements as rigorous as attainable. Reynolds remembers securing navy-grade evening imaginative and prescient gear and tenting out with fellow volunteers to try to file whale actions 24/7 in steady shifts.

While evening commentary has not been maintained, curiosity in whale watching has blossomed. At the height of the season, hundreds of folks flock to Cape Solander, and whale numbers have soared in current decades.

Reynolds noticed about 150 whales in his first yr of observations from Cape Solander. In 2019, he noticed greater than 3,000, with greater than 100 on some days.

His observations have been backed up by scientists, who’ve integrated the Cape Solander whale migration research’s findings into their very own analysis.

Dr Vanessa Pirotta, a marine biologist from Macquarie University, says southern hemisphere humpback whales have been hunted to close extinction by the Sixties, however since then their numbers have steadily grown, recovering to their first noticed inhabitants sizes by 2015.

With populations anticipated to peak at 40,000 over the subsequent 5 years, there are even calls to delist the humpback from the threatened species listing.

Pirotta cites these rising numbers as proof of profitable conservation efforts, and says the contribution of Reynolds and his fellow volunteers has been instrumental in documenting the whales’ resurgence.

Pirotta acknowledges the citizen scientists haven’t been academically skilled and don’t have entry to sure measurement applied sciences, however says the figures they generate correlate with systematic surveys performed in Queensland later within the migration.

“We have had Wayne there throughout the entire study period, training people and overseeing it. That gives us confidence in the effort.

“The amount of observation hours they have put in is just amazing. The cost of carrying that out in a funded scientific project would be impossible, you can’t achieve that level of observation.”

Pirotta first met Reynolds whereas learning for her grasp’s diploma, and has collaborated with him since gaining her doctorate, together with co-authoring academic journal articles primarily based on his findings.

While researchers like Pirotta would include theodolites to exactly measure distances from coastlines, Reynolds continued utilizing binoculars. He claims to have the ability to guess distances inside 20m of official accuracy.

Pirotta finds Reynolds’ ardour infectious.

“Wayne and I would be side by side all day, every day. It’s Wayne’s whale world,” Pirotta says.

“I love Wayne, I could sit in front of the ocean with him for hours.”

In 2019, Reynolds retired from main the research. He has turned his ardour to pictures, and spends a number of days every week taking photographs of whales on business vacationer vessels.

His journeys to Kurnell could also be much less frequent, however when he visited final week, volunteers at Cape Solander handled him as a legend of the operation.

As heavy fog worsened and fully hid the ocean, they retreated to a brief shed arrange for them, and stuffed Reynolds in on current happenings.

“There’s no whales right now, but at least we get to see Wayne,” one says.
