With the wind blowing a gale at Spittal Pond Nature Reserve in Smith's and the air filled with blinding spray from nearby pounding waves, Tuesday seemed like a good day for an angel.In this case, the angels were a group of CedarBridge Academy students calling themselves ‘Nature's Angels', who helped to guide more than 400 small children around Spittal Pond during the Bermuda National Trust's Annual Axis Children's Walk. The walk has taken place every year for the last 30 years, and participation has only grown during that time.Nature's Angel Swaynisha Berkley, 18, said it was the first time in the park for many of the children they were guiding and her as well.“I would definitely like to come back to the park again,” she said. “It has been a great day so far. The kids are very interested in the animals we are looking at today. They think they know everything. They know the type of trees they are looking at. We don't have to tell them anything.”Each guide was asked to lead the children to various stations set up around the park. The stations each had a speaker to tell the children about some aspect of ecology, geology or Bermuda's history. Former government conservation officer David Wingate, for example, manned a telescope in front of a secluded section of the pond, and talked to the children about birds and birdwatching. On this day, we followed Miss Berkley and CedarBridge Academy deputy head girl Killina Minors as they led the students around the pond until they came to scientist Mark Outerbridge. Dr Outerbridge held up an eel in the jar and told wide-eyed children from a camp group how the little creature had been found in a pond at Bernard Park in Pembroke.“They ask me over and over again, ‘is it alive?'” said Dr Outerbridge with a laugh. “I have to keep saying it is not alive. It is in a jar in chemicals. You don't want to touch it.”He said finding the eel alive in the area was a surprise to scientists as the Mills Creek canal and drainage ditches near Bernard Park, are known to be quite polluted.Guide Miss Minors said pollution was a deep concern to her.“It is concerning the way people are littering and harming the environment in different ways. We need to take a step back and say ‘look Bermuda, this is what is happening'. We are losing species and we need to be careful.”She said she was no stranger to the park. Her father had often brought her there on nature walks. She said there was no environment club at CedarBridge Academy, but it might be fun to start one.Miss Minors and Miss Berkeley and several other students were chosen as guides because of their passion for their environment and also their interest in young children. Both girls were interested in careers with children. On this day it was pretty clear that dealing with a bunch of children, mostly around the age of six or seven, took patience. Lance Furbert, at Portuguese Rock, told how he'd had to pluck one fearless child away from a windy, rocky ledge. Other children lagged and straggled and needed to be encouraged along some of the more difficult terrain such as the hill leading up to Portuguese Rock.Further along, a group of children perched on a rock listening to historian Ruth Thomas tell them the story of Jeffrey's Hole. One little girl clutched a large, brown teddy bear. During the days of slavery in Bermuda, an escaped slave hid out in the cave and was only caught when his girlfriend was caught taking him food.Sheets of salt spray washed over everyone as Ms Thomas drew out the tale. “Don't mind the spray,” Ms Thomas told everyone cheerfully. “It's good for you and it's been washing over me all day.” Nature's Angel Briana Boyd, 17, didn't seem to mind as she and another guide kept careful watch over the children.“We became Nature's Angels from our counsellors,” she said. “She told us about this community service opportunity, We thought it would be a great opportunity to spend the day outside and learn something about nature.”She said she had been to Spittal Pond before, “many times”.“It is a nice relaxing place to come, maybe on a Sunday stroll,” said Miss Boyd. “The kids love it. Our duties have been to inform them about the different plants and make sure they stay safe and get to the next station without getting lost. It is a nice experience. It is nice to put yourself out in the community.”Useful website: www.bnt.bm.
