You could read in May several times in the media that there were fewer Common Swifts (Apus apus) and Northern House-Martins (Delichon urbica) this year than in previous years. For example, a conservation organization reported on the results of the “Stunde der Gartenvogel”, which is equivalent the RSPB Big Garden Birdwatch number of these fast-flying insectivores declined by 40% less compared to 2006, when the first garden birds count (Stunde der Gartenvogel) was heralded.
But is it possible to deduce the extent of the loss of insect-eating birds from a momentary impression?
Meanwhile, both species are already longer in the country and the breeding season is almost over. Thus, the number of Common Swift has already passed its zenith again and since the beginning of August, no adult or this year’s specimens are present at some colonies in Brandenburg. House-Martins will be still present for several weeks but have bred already as well.
Thus, there are now good preconditions for answering the question Continue reading Common Swift and Northern House-Martin: a bad year in Germany?
Swifts (Apodiformes) in the family Apodidae are small birds which spend the majority of their lives flying. These birds have very short legs and never settle voluntarily on the ground, perching instead only on vertical surfaces. Many swifts have long swept-back wings which resemble a crescent or boomerang. There are 13 species occurring in Cameroon. In a Rockjumper trip to Cameroon in April 2017, swifts were encountered almost every day with Little swift (Apus affinis) and African palm-swift (Cypsiurus parvus) being by far the most common. The best shots of Swifts and Swallows during the trip you will finde in the gallery “Swift and Swallows over Sanaga River in Cameroon” .
Common Swift (Apus apus) are probably the 3rd most abundant and could be seen and photographed especially in the lowlands near the Sanaga River close to Edea in the south-west corner of Cameroon. A gallery of flying birds of Sanager river – Swallows and Swifts – show the great potential for birders and photographers.
Numbers of Common Swifts are declining throughout Europe. A third of British Swifts e.g. have been lost since 1995. But the reasons underpinning this decline are unclear. Scientists of the British Trust for Ornithology (BTO ) are involved in a project aiming to address Continue reading Swifts over Sanager River/ Cameroon
Während einer Reise vom 1. bis zum 8. Juli nach Rumänien und Bulgarien konnte eine bemerkenswerte Beobachtung in den rumänischen Karpaten im Bild festgehalten werden. Ein Männchen und ein Weibchen des Alpenseglers (Apus melba) wurden gesehen, wie sie unter einem Felsvorsprung in einer Steilwand flogen und dabei über mehrere Sekunden die Begattung vollzogen. Dies konnte in einer wunderschönen Schlucht im Piatra Craiului Nationalpark nahe der Stadt Zărneşti (Zarnesti) mit der Kamera fotografiert werden. Zarnesti liegt südlich von Braşov (Kronstadt) und befindet sich ca. 180 km entfernt von Bukarest, der Hauptstadt von Rumänien.
In der westlichen Paläarktis leben Alpensegler vor allem in Südeuropa, hier insbesondere in Gebirgen. Wie Mauersegler (Apus apus) wandern sie über den Winter in das südliche Afrika. Wie in dieser Schlucht zu sehen, baut diese Seglerart ihr Nest in der Regel Continue reading Alpensegler: eine Paarung im Flug
Am 05.05.14 konnte auf Grundlage einer Meldung in Ornitho.de bei einem Besuch der Schiersteiner Wasserwerke in der Umgebung von Wiesbaden im Rheingau ca. 50 km westlich vom Frankfurt Stadtmitte mindestens ein singender Drosselrohrsänger entdeckt werden. Es konnten einige Fotobelege gemacht werden. Aktuell – zumindest bis vor 2 Tagen – ist mindestens Continue reading Nachweis des Drosselrohrsänger (Acrocephalus arundinaceus) am Mittelrhein
During a trip from July 1st till 8th 2013 to observe birds in Romania and Bulgaria a remarkable sighting could be noted. A couple of Alpine Swift (Apus melba) was seen flying below a crag in a steep rock and copulated for several seconds. This could be seen in a beautiful gorge near the town of Zărneşti (Zarnesti), in the Piatra Craiului Nationalpark. Zarnesti is located south of Brașov (Brasov) approx.. 180km away from the capital of Romania, Bucharest.
In the Western Palearctic Alpine Swifts breed in mountains mainly in southern Europe. Like Common Swifts, they are migratory, and winter in southern Africa. As happened in that gorge the species builds its nest on cliff faces typically. Alpine Swifts build their nests in colonies in a suitable cliff hole or cave. It is well known, that Alpine Swifts spend most of their lives in the air, living on the insects they catch but up to now, a copula in flight could not be photographed. At least Bird-lens could not find a photo on the web. Consequently Bird-lens is proud to show images of a flight copula of this remarkable species.
As is mentioned in the „Handbuch der Vögel Mitteleuropas“ (Handbook of the birds of Central Europe), Volume 9 “Columbiformes – Piciformes” by Urs N. Glutz von Blotzheim, the male Alpine Swift usually holds the female with the beak in the neck and with the feet in the back plumage of the quiet female partner in copulation. While the female raises its tail, the male winds down his abdomen. For the Common Swift (Apus apus), also a copula in flight is described. Bird-lens is proud to show images of a flight copula of the much scarcer species Alpine Swift. A copula in flight resembles a courtship flight. During courtship Continue reading Copula in flight of Alpine Swift in Romania´s Carpathians
This morning all 4 species of Sylvia-Warblers which regularly occur in Germany could be seen. First the male of a Blackcap (Sylvia atricapilla) showed up in the first light of this chilly but sunny morning. Then a beautiful singing individual of a Common Whitethroat (Sylvia communis) could be seen very near to a observation tower which is located on the eastern end of the old gravel pit. A Lesser Whitethroat (Sylvia curruca) showed up briefly afterwards. And finally even a silent Garden Warbler (Sylvia borin) could be seen catching a caterpillar in a dense bush.
When photographing it was obvious to see that breeding is in full swing. Singing and other territorial habits were rare and normally quite short – with the exception of the singing individual of a Common Whitethroat and a Common Nightingale (Luscinia megarhynchos).
A sunny morning with clear sky after several rainy days was a good reason to make the trip to that abandoned gravel pit which is now a nature reserve and try to photograph some special birds.
This early morning on a sunny day (but quite cold in the first hours) was a real pleasure – even from the point of ornithology. In addition to the shots of the Warblers, it was possible to see and photograph birds like European Turtle-Dove (Streptopelia turtur), Common Cuckoo (Cuculus canorus), Eurasian Golden-Oriole (Oriolus oriolus), Sand Martin (Riparia riparia) and Hawfinch (Coccothraustes coccothraustes). Good contributions to the bird-lens portfolio and possible to see here in the Continue reading All 4 Sylvia – Warblers in Weilbacher Kiesgrube near Frankfurt
Last weekend, you could observe heavy traffic in the skies over Frankfurt/ Germany. Although winter is not ready to lower its grip the first returning migrants already point to the imminent end of the cold season. In recent weeks, Eurasian Skylarks (Alauda arvensis), and Northern Lapwings (Vanellus vanellus), were seen already on their return. Particularly striking are currently the Common Cranes (Grus grus) flying in wedge-shaped formations over western Germany. On the 9th of march you could see at least 30 individuals over the outskirts of Kelkheim/ Main-Taunus-Kreis. The southern slopes of the Taunus are one of the pathways of the western migration corridor of these tall, slender birds before they are heading further north of the Wetterau
For the Bay of Cologne, which is 200km further north located, the long-term statistical average is between 5th and 13th of March. What this mean in terms of quantity you can see by the fact that highest count in crane observation was made by the NABU Aachen (further to the west), who observed more than 8,000 cranes in the region between that time period (5th and 13th of March in 1991).
The birds spend the winter mainly in sunny Spain or France. Their main wintering area is located in the Extremadura in western Spain. There, the cranes in the clear Mediterranean oak forests searched for the fruits of holm and cork oaks. On the way back to their breeding grounds, the cranes Germany crossed on quite a narrow corridor toward the southern shores of the Baltic sea in the state of Mecklenburg-Vorpommern.
But there are even more flocks of birds expected in the coming weeks: Blackcaps (Sylvia atricapilla), Continue reading Migratory birds herald spring
There are not too many foreign birdwatchers coming to the middle of Germany for just birding. But Frankfurt Airport (FRA) is the gateway to continental Europe. Many airlines use the Airport as a hub for connecting flights all over the world. If you have spare time between two flight and you are a birdwatcher, you might be interested to know, where you can find good places to stretch your legs, enjoy fresh air and enjoy birding for typical european birds. One of these places is only 15 minutes away from the Frankfurt Airport. This is the Schwanheimer Duene (Dunes of Schwanheim) located in a southern outskirt of Frankfurt. In so far, the area is more or less the same distance than the Langener Waldseen. But whereas these lakes, situated just 2 km east of the runway of Frankfurt AP, are a highly frequented recreation area in summertime, the Schwanheimer Duene is especially good in spring and summer. Thus an excellent alternative to the Langener Waldseen which are very productive in wintertime.
The Schwanheimer Duene is one of the few inland dunes in Europe. It was established after the last ice age of sands that have been blown out of the riverbed of the River Main. Then, a forest grew on it. In the last century farmers cleared the forest and put on cherry meadows. Several dry periods ended these attempts in the second half of the 19th Century. The dune devasted and started to wander. Between 1882 and 1890 the dune moved aground to its present location.
Following the desolation a typical plant community of inland dune developed, which can be encountered up to nowadays. This plant community is called Continue reading Birding around Frankfurt Airport – Schwanheimer Duene
