Kraniche kreuzen

This cache shows you the kranichvillage Langenhagen. It is a tour by the village with beautiful outlook on protected area. If you are owner of binoculars, this is a perfect chance to use it! All stations are at the street, so you can drive by bicycle/car. But I find, by walking its most beautiful.

The start-coordinates lead you to an infoboard directly beside the observationhut. Here you can read how large the protected area is. = aaa (meant is the alone standing board, not the board on the hut)

The coordinates 53°34.780’ N und 12°01.483’ E lead you to a further infoboard. Which number has the kranich? = b

Here (53°34.729’ N, 12°01.626’ E) you can sit down and enjoy the outlook. Besides you throw a view to the left. You discover a tree with a birdpension. This tree has a mark with the number cc. (don’t conside zeros)

Follow the street and you will see the infoboard “Leben am See”. Each shown animal has a number, with which you can solve the following task:
Blässhuhn + Blaugrüne Mosaikjungfer + Drosselrohrsänger + Eisvogel + Graureiher + Löffelente + Plattbaulibelle + Schilfrohrsänger + Schnatterente + Sumpfohreule + Tafelente + Tüpfelsumpfhuhn + Zwergdommel + Zwergtaucher = ddd

If you visit now the coordinates 53°34.318’ N and 12°01.465’ E then you stand before a house where you can read somewhat on the roof. Each letter consists of a certain number of black roofing tiles. Solve this task:
(G x N) + (A x M) + (R x 2) = eee

Now solve the last task:
(b x cc) + eee = fff
aaa + ddd = ggg

The cache is hidden outside the village (1,5 km) in a tree. Sometimes you can see there a green manikin.
