Land of Beavers!

I use to find signs of Beavers occurrence regularly during my walks in the nature in the surroundings of Bratislava. Have a look what I found yesterday:
tree with freshly nibbled wood, next to the Danube's seepage channel
marks of beaver's teeth
another site, signs of beavers again: small creek along the road, red arrow shows to the dam
creek with the beaver dam

100 urban bird species this year and counting...

I was guiding a bird walk in Petržalka this morning. Our targets were common bird species of local waterbodies as Mute Swans, Coots or Black-headed Gull. We were exploring quiet corners of nature in this large borough of Bratislava, mostly comprised of blocks of flats. Last year in the beginning of November (9.11.2012) we observed Black-throated Loon (Gavia arctica) on Lake Veľký Draždiak. Today we had a reprise. Beside me and my colleague Katka there were also participants of our guided walk, that have spotted this unusual bird as well. Until today I have observed 99 various bird species in the urban areas of Bratislava this year. It couldn't be any better than reaching magical "100" with such a stunning bird as Black-throated Loon really is. I tried to make proper documentation so here are the results: 
Black-throated Loon (Gavia arctica)
Black-throated Loon (Gavia arctica) with Mute Swans (Cygnus olor)
Black-throated Loon (Gavia arctica) before diving
Black-throated Loon (Gavia arctica)
Black-throated Loon (Gavia arctica) in the rain




I think you may have enough of this Loon, so here is a little bonus of the other species observed today. Kingfisher was another addition to my urban yearlist.
Treecreeper (Certhia sp.), probably common one (C. familiaris)
Kingfisher (Alcedo atthis) - nr. 101 in my urban Bratislava yearlist
Coot (Fulica atra)
adult Black-headed Gull (Chroicocephalus ridibundus) in winter plumage

First winter guests on Danube

I made another birdwatching bike ride. Despite it is November already, the weather was pleasant. I rode along Danube and I made several stops to check the surface of Hrušovská zdrž water reservoir for newly arrived winter or migration guests. I got my only second sighting of Shelducks (Tadorna tadorna) in Slovakia. Ten of them were swimming in compact flock along with thousands of other ducks. First Goldeneyes (Bucephala clangula) appeared. There was a group of 13 Goosanders (Mergus merganser). Beside Tufted Ducks and Mallards the numbers of Teals (Anas crecca) and Wigeons (Anas penelope) are arising. I counted 83 Teals and c130 Wigeons today. I spotted only 2 Pygmy Cormorants (Microcarbo pygmeus), but at least I know first of these unusual migrants are here. Pygmy Cormorants migrate not southwards but to the northwest from the Danube delta. In the peak of winter we could have here up to 1000 birds. In addition I observed Kingfisher (Alcedo atthis) for a while and flyover of a White-tailed Eagle (Haliaeetus albicilla).  Great Egret (Egretta alba) with something like tumour on its leg need to be mentioned as well. I'm not sure if it will survive winter.

Afternoon bike birding in Petržalka

Forecast for the next days didn't look well, so I decided to take a bike ride to Petržalka. I checked Incheba building if I can spot Peregrine Falcon. It was there! Then I visited Lake Veľký Draždiak. Birds on this lake were really close as they are used to pedestrians. I had nice views of Mute Swans, Coots and Mallards. Great Crested Grebe appeared in the middle of the lake. Just few hundreds meters away is Lake Malý Draždiak with small wetland next to it. I found there 2 Mute Swans, 2 Coots, Little Grebe, Grey Heron and Great Egret. Jay and Green Woodpecker flew over my head.

Weekend in Hortobágy National Park

We have spent last weekend in Hungary. Our main target was Common Crane (Grus grus) migration stop in Hortobágy National Park. Beside it we have visited Hungarian Grey cattle fair. We tasted famous local cuisine and explored vast steppe country also known as puszta. Two of the bird highlights we spotted from bus while driving on highway. On Slovak-Hungarian border we observed flock of c30 Great Bustards (Otis tarda). Adult Imperial Eagle (Aquila heliaca) was flying next to the highway 85km east from Budapest. The count of Common Cranes in the area was one of the largest in the last years - c85000 birds were counted in Hortobágy NP. The best moment came during Saturday sunset. About 15-20000 Common Cranes landed on Kondás fishpond while we were observing them from hides and platforms just 1km away. Aside of the Cranes we spotted during the weekend 5 White-tailed Eagles (Haliaeetus albicilla), Peregrine Falcon (Falco peregrinus), up to 50 Bearded Reedlings (Panurus biarmicus), tens of Pygmy Cormorants (Microcarbo pygmeus), Curlews (Numenius arquata), Spotted Redshanks (Tringa erythropus) or Little Owl (Athene noctua) - other pair was calling just few metres apart of our accomodation in Patkós csárda. Complete list of observed bird species you can find in the end of this post.
