About this place
Analyze Haliaeetus albicilla apex nesting above Baltic raised Sphagnum peatlands and millennia-scale carbon sequestration.
For kids: Soar to the top of a giant Latvian spruce tree where barn-door-winged sea eagles watch over ancient mossy bogs!

What to look for
- Emergent spruce crown eyrie — Haliaeetus albicilla perennial platform. Locate the wind-exposed emergent conifer crown supporting an apex eagle eyrie
- Raised Sphagnum peat dome — Ombrotrophic Sphagnum carbon sink. Centre the ombrotrophic raised bog dome where Sphagnum acidifies porewater
- Shallow pike & coot lake — Esox lucius & Fulica atra prey zone. Scan the shallow eutrophic lake margin supplying pike, bream, and waterbirds

Ask together: Why does an eagle keep adding fresh pine twigs and soft hay to the very same treetop nest year after year?
Field quiz
Kids' question: Why doesn't dead plant stuff rot away quickly inside a wet Latvian Sphagnum bog?
- The moss makes water sour like lemon juice and leaves almost zero air for rot-bugs
- Tiny bog fairies vacuum all leaves every Friday
- Boiling underground lava toasts the moss dry
Answer
The moss makes water sour like lemon juice and leaves almost zero air for rot-bugs
Adults' question: What biochemical mechanism makes ombrotrophic Sphagnum bogs among Earth's densest terrestrial carbon sinks?
- Cation exchange releasing H+ ions, phenolic sphagnan compounds, and waterlogged anoxia inhibiting phenol oxidase
- Rapid calcification by marine coral polyps inside peat pores
- High-velocity oxygen bubbling from deep limestone geysers
- Complete sterilization by ultraviolet glare off snow year-round
Answer
Cation exchange releasing H+ ions, phenolic sphagnan compounds, and waterlogged anoxia inhibiting phenol oxidase

- By day
- Adult white-tailed eagles, eaglets, delivery of pike & vocalizing cranes Operated by the Latvian Fund for Nature since 2015, Durbe is among the longest continuous apex-raptor ethology streams in Europe.
- By night
- Roosting sea eagles on spruce boughs, calling tawny owls & roe deer barking Resident Courland pairs duet at first dawn light even in midwinter to advertise territory occupancy to floating subadults.
