Spring birds migration at Presqu’ile National Park, twenty minutes east of Cobourg
Owen point trai, finally arrived ! Just spotted a yellow warbler
A hug , sister to sister , so excited
Forbidden zone ? Ah! Marshes and dunes . Lots of shorebirds that we didn’t even know
Balancing on the beam . Ladies and gentlemen , this is Eden show !
Found a skeleton of a fish . Mommy ! Excitement to explore
Lots of shells - it feels soft and good when you walk on it , but be careful ! ‘Poinky’ Eden said!
And reeds - an invasive species ? It’s wet in the spring, dry in the summer , very few species can last through this. Marsh land
Spring is the birds migrating season . Best time to come us 6am! No predators , it is quiet
Later in the summer the lake dries out . Perfect ground for sandpipers . We have to come back !
Impressive distance covered by shorebirds !
The forests at Presqu’ile are made up of 40%-60% ash trees.
Schuner Speedy left from York to Kingston . It was not in a good condition . The last time it was seen was close to Presqu’ile .
Big waves and strong currents at the Presqu’ile point !
Measuring water quality . We may not have held the thermometer for too long to measure the temperature of water but it was fun . We also found fossils !
The measurements . Good quality , no clorine , the water is soft - no minerals
The way Presqu’ile was formed , limestone is easily broken off . Lots of 350m fossils on the beach . Lots of pebbles on this part of the peninsula .
The lighthouse at Presqu’ile Point is the second longest continually open light house on Lake Ontario, with new cupola installed in the fall of 2023. It opened in 1840. It was the first light an early mariner would encounter east of Toronto heading towards Kingston. For 95 years the light keeper would carry fuel up 80 steps to keep the light shining on stormy nights, until electricity reached the lighthouse in 1935.
The girls loved running around it
Yummy sausage at the Big Apple on the way home
Petting zoo ! Look at the turkeys
This goose seems to have a pillow for its head as per Kyra!
Feeding a Billy goat! Eden got all the pieces from the ground to give to the goat , she knew exactly what to do , smart
We like to climb . This cow - why not?
Presqu’ile is a tombolo- an island attached to the mainland by a sand or gravel bar. The campground areas are in the island and the long straight entrance road to the campgrounds travels down the middle of the sandbar. it is that bar that makes up the beach area on its western side.
The fossil found is a trilobite. We also found a gastopod but left it on the beach. These fossils would need to be returned to the Nature Centre.
- The Presqu’ile tombolo is the largest on freshwater in Canada, and probably the world. It is the nature of tombolos that they are made up of a variety of habitats, which leads to Presqu’ile’s next significant feature – biodiversity.
- Presqu’ile has great biodiversity. For such a small area it has a remarkable eight distinct habitat. More habitats mean more diversity in the plants and animals that live here. Our habitats are sand, beach, dunes, pannes – wetlands between dunes, conifer forest, the deciduous forest, old fields/Meadows, conifer plantations, and the marsh/bay complex. Can you guess which is the rarest habitat? It is pannes, a globally rare habitat. It is best appreciated in spring as a frog reading ground and in the fall when many unusual flowers bloom.
- Presqu’ile is a migration trap. The tombolo’s position as a peninsula sticking out into Lake Ontario and it’s many habitats makes it a magnet for migrading birds and insects. They rest here after crossing the lake coming north and wait here for the right winds when heading south. Ducks in March, songbirds in May and shorebirds in late May and again in September, significant concentrations of monarch butterflies and green darker dragonflies in early September as they had south.
- Presqu’ile has fossils. The rocky shorelines have an abundance of fossils that are 450 million years old. This represents a piece of Ontario’s ancient history - the Ordovician sea that once covered this area.
- Presqu’ile’s marsh is magnificent. The marsh is the largest protected marsh on the north shore of Lake Ontario. It is part of a shoreline marsh system that is disappearing from the shores of our Great Lakes. The best way to experience the marsh is along the 800 m boardwalk.

The Ordovician period (425-500m years ago) so the rise of new animal groups are great importance. Bone fragments are evidence of the oldest vertebrates, but we do not yet know much about these fish like creatures. Here’s how fossil is formed: 1- animal dies, and shell is buried in the sand, 2- sand hardens to rock, shell interior unfilled. 3. Shell material dissolved. Cavity wall is mold of shell. 4. Dissolved chemicals fill mould to form cast.5. Both mould and cast are fossils, replicas of the original service.
