Ma zavalite telo, kratke koncetiny, ocas a krk, velkou hlavu a sidlovity zobak. Vrch hlavy a tela je sedomodry, letky jsou tmave. Cerny pruh, ktery se tahne od korene zobaku pres oko az k tylu, byva u samic ponekud uzsi. Lice a hrdlo jsou belave, spodina zlutooranzova, boky a spodni krovky ocasni narudle, u samce velmi tmave, oci cerne a koncetiny zlutooranzove..
Rozsireni
Brhlik lesni je rozsiren na rozsahlem uzemi Eurasie a v severozapadni Africe. Je staly. Zdrzuje se prevazne v listnatych a smisenych lesich se starymi stromy, bezny je vsak take v zahradach a mestskych parcich. Nejhojneji se vyskytuje v nizinach, ve vyssich nadmorskych vyskach je jiz vzacnejsi..
Potrava
Jedna se o teritorialni druh, ktery se kazdorocne vraci na stejna hnizdiste. Dobre splha po stromech, jako jediny evropsky pevec i hlavou dolu. Potravu, kterou tvori zejmena drobny hmyz, vyhledava ve skvirach v kure, nebo tesne pod ni. V zime se zivi hlavne semeny, casto navstevuje krmitka spolu se sykorami. Celorocne si navic aktivne dela zasoby, ktere pak postupne vyhledava.
Rozmnozovani
Hnizdi jednou rocne od brezna do cervna v dutinach stromu, nejcasteji vydlabanych nejakym datlovitym ptakem (nepohrdne ani budkou), zvlaste pak ve starych dubech. Pokud je vletovy otvor prilis velky, zazdi ho castecne hlinou, aby dovnitr nemohl zadny vetsi druh. Dutinu vystyla prevazne kousky borove, modrinove, nebo dubove kury. Ve snusce byva 5–9 bilych, hnede skvrnitych, 19,6 x 14,7 mm velkych vajec, na kterych sedi samotna samice 14–17 dni. Mladata hnizdo opousteji po dalsich 22–25 dnech.
Celou serii se snazime pomoci nasim ptacim kamaradum usnadnit jejich nelehky ptaci zivot zajistenim potravy pres zimu. Jednou z moznosti, jak ptakum pomoci je prave geokrmitko, ktere jsme spolecne vyrobili na nasich oddilovych schuzkach a umistili.
Proto Vas prosime, abyste s sebou vzali i nejakou vhodnou potravu do krmitka.
Co do krmitka patri:
-
semena (slunecnice, proso, konopi, lnene seminko, repka)
-
drcena jadra vlasskych a liskovych orechu
-
v obchodech lze zakoupit primo specialni michane smesi pro krmeni ptaku
-
na hacek umisteny na krmitku muzete zavesit luj nebo lojove koule
Co do krmitka rozhodne nepatri:
-
zbytky z kuchyne
-
slane potraviny
-
prepaleny tuk
-
zkazene potraviny
Odmenou Vam pak bude vesele ptaci prozpevovani.
-
Kdo chcete, muze si z kesky vzit letacek, z ktereho se dozvite zajimavosti nejen o prikrmovani ptaku, ale i o stavbe budek a krmitek. Pak si sami doma budete moct nejakou budku ci krmitko vyrobit a pozvat tak ptaky i k vam na zahradu.
Cestou od kese se pak muzete pokusit najit a popripade i vyfotit nejen modrinky, ale i dalsi stravniky.
Uspesny odlov preji Brontosauri z pardubickeho Brda! http://brdo-pardubice.brontosaurus.cz>
........................................................................................................................................................... Welcome at Eurasian nuthatch! Welcome at the first stop of our bird series. All the caches were made by children attending children’s club BRDO Pardubice, which is part Hnuti Brontosaurus movement ( brdo-pardubice.brontosaurus.cz). This cash will teach you about life of Eurasian nuthatch. When you go hunt for this cache, take some bird food with you, please. The reward for you will be stickers, bookmarks, fridge magnets or buttons - all with natural theme. Please, try to keep the theme of the cache during exchanging stuff. Thank you! Eurasian nuthatch Description Eurasian nuthatch has approximately the same size as sparrow. Nuthatch is 13 - 14, 5 cm long with 23 - 27 cm wingspan. It has a stocky body, short legs, tail and neck, large head and thin beak. The top of his head is blue-gray. Black stripe that extends from the base of the beak through the eye to the rear is thinner in females. The cheeks and throat are whitish, the flanks and lower belly are orange-red, black eyes and yellow-orange legs. Distribution Eurasian nuthatch breeding range extends across Eurasia and in the southwest Africa. Nuthatch is mostly sedentary. The preferred habitat is mature woodland with large, old trees, but it can be found also in the gardens and city parks. Nuthatch can be easily found in lowlands, but is rarer in higher attitudes. Feeding This is a territorial species that annually returns to the same nesting site. Nuthatch can climb the trees very well. It is the only European songbird which can climb the trees even upside down. The food consists mainly from little insects, which nuthatch founds in the tree bark or just beneath. In the winter, nuthatch eats mostly seeds and often visits bird feeders together with tits. All year also makes stocks, which gradually seeks out. Breeding Nuthatches nest once a year from March to June in tree hollows, most often hollowed out by some other bird especially in old oaks, but they nest also in bird boxes. If the hole in the tree (or bird box) is too large, they brick it partly with clay, so bigger birds can’t fly in. In the clutch there are laid 5 - 9 white eggs with brown spots. The size is 19,6 x 14,7 mm. The female incubates them for 14 - 17 days. Chicks leave the nest after further 22-25 days. With the whole series we are trying to help to our bird friends with their uneasy life during winter by providing them food. One way, hot to help them is geo bird feeder, which we made together during our meetings. So please, take some bird food with you when you go hunting for the cache. What is good for the birds: • seeds (sunflower, millet, hemp seeds, linseed, rape-seed) • crushed walnuts and hazelnuts • ready-made feeding mixtures are available on the market • suet or balls of suet with seeds and nuts can be hung on the hook at the feeder What will not do the birds good for sure: • kitchen scraps • salty food • burnt fat from frying • decayed food The birds will reward you with merry singing and chirping. Leaflets are provided in the geocache for everyone who may be interested. Take one and read about bird feeding or how to make your own nest box or a feeder. The information will help you attract birds to your own garden or any favorite place where you would like to enjoy them. On the way back, you may like to look for some of the nest boxes we placed all around, watch their inhabitants and perhaps make a photo of them. Good hunt! Yours Brontosaurus
