Geocache Description:

Purkki on helppo löytää. Älä irrota narua pois. Kierrä purkki auki. The cache is easy to find. Don´t take the rope of. Turn the box open.

Mustarastas (Turdus merula) on varpuslintuihin kuuluva rastas.

Koiras on hiilenmusta ja nokka keltainen, naaras on tummanruskea selkäpuolelta, vaaleampi alta ja sen nokka on ruskea. Nuoren koiraan nokka on tumma pitkälle kevääseen. Nuori lintu on erotettavissa vanhasta haalistuneiden siiven isojen peitinhöyhenten perusteella.

Pituus 24,5–27 cm, siipien kärkiväli 34,5–40 cm paino 75,5–110 g.

Laulaa puun korkeimmalla oksalla tai muualla korkealla olevassa kohdassa esim. maston huipulla. Laulu on kaunista melodista lurittelua, jossa on huilumaisia ääniä ja joka kuuluu kauas kesäiltoina ja aikaisin aamuisin ennen auringon nousua. Se on monien mielestä Suomen kaunein linnunääni. Lentoääni tilhimäinen sirinä. Varoittelee ”tsuk-tsuk”, ja oikein hädissään ollessaan viheltää erittäin korkeaa säveltä. Hämärissä kuulee jankuttavaa plinkutusta minuuttikaupalla yhteen menoon.

Vanhin suomalainen rengastettu mustarastas on ollut 9 vuotta 2 kuukautta 15 päivää vanha.

The Blackbird, Common Blackbird or Eurasian Blackbird (Turdus merula) is a species of true thrush which breeds in Europe, Asia, and North Africa, and has been introduced to Australia and New Zealand. It has a number of subspecies across its large range; a few of the Asian subspecies are sometimes considered as full species. Depending on latitude, the Blackbird may be resident, partially migratory or fully migratory.

The male of the nominate subspecies, which is found throughout most of Europe, is all black except for a yellow eye-ring and bill and has a wide range of vocalisations; the adult female and juvenile have mainly brown plumage. This species breeds in woods and gardens, building a neat, mud-lined, cup-shaped nest. It is omnivorous, eating a wide range of insects, earthworms, berries, and fruits.

Both sexes are territorial on the breeding grounds, with distinctive threat displays, but are more gregarious during migration and in wintering areas. Pairs will stay in their territory throughout the year where the climate is sufficiently temperate. This common species has given rise to a number of literary and cultural references, frequently related to its melodious song.
