Vrabec polni
Popis Vrabec polni dorusta 12,5 - 14 cm, v rozpeti kridel meri 21 cm a jeho hmotnost se pohybuje mezi 20-24 g a je o neco menši nez vrabec domaci, s kterym byva casto zamenovan. Podoba se hnedym, cerne prouzkovanym hrbetem, šedavou spodinou tela, cernym podbradkem, uzdickou a zobakem a bilou paskou v kridlech, ale liši se nasledujicimi znaky: celym vinove rudohnedym temenem, ciste bilymi stranami hlavy s vyraznou cernou skvrnou na tvarich, menšim cernym podbradkem neprechazejicim ve velkou cernou skvrnu na hrudi a úzkym bilym obojkem. Pohlavi jsou stejna, mladi ptaci jsou zbarveni matneji.
Rozšireni
Zije ve vetšine Evropy a Asie (krome nejsevernejšich koncin), zavlecen byl i do Severni Ameriky a Australie. Prevazne staly druh, ptaci ze stredni a severni Evropy však mohou tahnout az do Stredomori. Vyhledava otevrenou krajinu se sady, krovinami a lesiky. Pokud hnizdi v obcich ci mestech, najdeme ho spiše na jejich okraji nebo v zahradach. V CR hnizdi pocetne na celem územi, hlavne v nizšich a strednich polohach. Pocetnost se na našem územi mirne snizuje, v letech 2001–03 u nas hnizdil v poctu 400 000–800 000 paru.
Potrava
Potrava je prevazne rostlinna, mene je zastoupena i zivocišna slozka. V porovnani s vrabcem domacim konzumuje vice semen plevelu nez kulturnich rostlin a neoklovava ovoce, škody pachane na zemedelskych plodinach jsou tak znatelne nizši nez u vrabce domaciho.
Rozmnozovani
Hnizdi jednotlive i pospolite. Pary jsou trvale a setrvavaji spolu po nekolik let, obcas se však vyskytuji i pripady polygamie a bezne dochazi k mimoparovym kopulacim. Hnizdo je nejcasteji v dutinach stromu nebo v budkach, mene take ve skalnich šterbinach, šterbinach v hlinikovych stenach, otvorech panelovych domu ci ve starych hnizdech dravcu, capu aj., jen vyjimecne i v korunach stromu. Hnizdo stavi oba ptaci z rostlinnych stonku, peri, mechu, vetvicek, jehlici a korinku, hnizdni kotlinku vystylaji jemnejšim rostlinnym materialem a perim. Hnizdi vetšinou 3x rocne od dubna do cervence. Snuška cita 4–6 bilych, po celem povrchu tmave skvrnitych vajec o rozmerech 19,1 x 14,2 mm. Snašena jsou denne a sezeni zacina od sneseni predposledniho nebo posledniho vejce. Na vejcich sedi po dobu 12–13 dnu oba ptaci. Mladata jsou krmena obema rodici a hnizdo opoušteji po 15–16 dnech. Samostatnosti dosahuji 8–10 dnu po vyvedeni a nasledne se shromazduji do hejn, ke kterym se po vyhnizdeni pripojuji i dospeli ptaci. Pohlavni dospelosti dosahuji ve 2. roce zivota. Nejvyšši znamy vek je 13 let a 1 mesic.
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 vrabce, ale i dalsi stravniky. Uspesny odlov preji Brontosauri z pardubického Brďa! http://brdo-pardubice.brontosaurus.cz

Welcome at Eurasian Tree Sparrow
Description
Eurasian Tree Sparrow grows 12.5 - 14 cm, the wingspan is 21 cm and weighing between 20-24 g and is slightly smaller than a house sparrow, with which is often confused. They resemble with brown, black ribbed back, grayish scum body, black jowls, Chinstrap and beak and white tape in the wings, but they differ by the following features: the entire wine-red-brown on top, pure white sides of the head with a distinct black spot on the cheeks, a smaller black jowls which does not ganges to big black stain on his chest and a narrow white collar. The sexes are identical, the young birds are stained darker.
Distribution
He lives in most of Europe and Asia (except the northernmost coasts) and was introduced into North America and Australia. Mostly stays a tone place, birds from central and northern Europe can pull up to the Mediterranean. Searches for open countryside with orchards, shrubs and woodland. If nests in villages and towns, we find it rather on their outskirts or in the gardens. In the Czech Republic nests throughout the whole country, mainly in the low and medium altitudes. Abundance in our territory slightly reduced in the years 2001-03 in our nesting in the number of 400 000 to 800 000 pairs.
Food
The diet is predominantly based on plants, livestock component is less represented. In comparison with the house sparrow consumes more weed seeds of cultivated plants and does not damage fruits, crops etc.
Reproduction
It nests singly as well as together. Couples are permanent and remain together for several years, but sometimes there are also cases of polygamy and commonly occurs by coupling outside the couple. The nest is usually in hollows of trees or in booths, less well in rocky crevices, fissures in aluminum walls, holes prefabricated houses or old nests of raptors, storks and others., rarely even in the trees. The nest is build by both birds from plant stems, feathers, moss, twigs, pine needles and roots, nesting valleys line the finer plant material and feathers. They nest usually 3 times a year from April to July. 4-6 includes a bunch of white, over the entire surface of dark speckled eggs with dimensions of 19.1 x 14.2 mm. Eggs are laid daily, starting from ablation penultimate or last egg. Both birds sit on the eggs for 12-13 days. Chicks are fed by both parents and leave the nest after 15-16 days. The chicks leave the nest after 8-10 days led out and then gather in flocks, which, after leasing the nest, are joined by adult birds. They reach sexual maturity in the second year of life. The highest known age is 13 years and 1 month.
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 balls of suet with seeds and nuts can be hung on the hook at the feeder
What will not be good for sure:
- kitchen scraps
- salty food
- burnt fat from frying
- decayed food
The birds will reward you with merry singing and chirping. J 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
