Migration: Woodchat Shrikes, Wheatears and Montagu's Harriers

One of my own personal sights of spring, is that of the first sightings of Montagu's Harrier's return to Europe. The birds often return in pairs and the males waste no time in displaying, claiming territory and mating, suggesting that prenuptial bonding has taken place en route or even in their wintering grounds.

Spring migration starts in ernest during March each year on The Strait of Gibraltar. The numbers of different species making the annual crossing back to Europe from their wintering ground in Africa steadily picks up pace and becomes a visible sight with the sheer concentration of numbers.

Montagu's Harriers have a very light and almost bouncing, easy flight. Their slim wings carry them in a seemingly effortless way searching for prey, low along field margins and rough ground

I was waiting for this lovely Black-winged Kite to turn around and face the camera when I just caught a glimpse of something interesting come into view. I instinctively shot off a few frames and managed (just) to get a lovely male Black-eared Wheatear passing through the field of view. I particularly like this shot because it shows that there's such a lot happening during the spring migration and basically anything can happen and quite a lot of early migrants and vagrants do turn up. Last weekend a Moussiere's Redstart male was seen at Punta Camorro, Tarifa. I looked for it a few days later but it was nowhere to be seen. I still haven't seen a Moussier's Redstart in Spain, or a Common Bulbul for that matter and both are just across the other side of The Strait.

Common Linnets can be seen in their thousands at present and along with Goldfinches and Serins provide food for many migrating or wintering raptors including harriers, kestrels and Black winged Kites

Adding a real splash of colour along the canal banks, reed-beds and wetlands is the Purple Swamphen

Black Storks at first light are always special to see. Having roosted in the open during the night, they'll continue their journey northwards

Most of the Great Spotted Cuckoos have moved through our area having completed their 'egging' in the nests of Common Magpies who's numbers have been increasing over the years in this part of Cadiz province. I suspect that more opportunities to parasitize the nests of Common and Azure-winged Magpies occur where the populations of both magpies are greater in the west and the north. This flight photo of a Great Spotted Cuckoo taken last week shows how long their tails are - despite the moult!

A story unfolded this week about this particular Osprey that I photographed recently at the Presa de Barbate. The bird had been ringed and also had a plastic colour identification ring on it's left leg. A report was sent off and a reply with details came back quickly from Dr Daniel Schmidt from NABU, the German equivalent of the RSPB. The bird is six years old and was ringed in the Brandenburg area in NE Germany on the 5th July 2006

This is another Osprey seen on migration along the banks of the Río Guadalquivir

We have had a lot of Swift migration with Common Swifts, Pallid, Alpine (above) and Little Swifts

Here little Swifts can be seen fairly regularly along the coast on The Strait and in the Chipiona areas to the Guadalquivir mouth at the town of Sanlucar

A short-toed Eagle hunts along one of the open valleys

Griffon Vultures often find a dead animal on the vast open areas of the Barbate Marismas and the Military Zone close to the coast. Looking behind the bird is the Río Barbate and in the distance our house. Not a bad area to live in and it's surprising what flies over our garden and our guest house Hoopoe cottage

Within the Marismas Tawny Pipits are beginning to arrive and begin their breeding season

Common Cuckoos are always great to see, especially as numbers seem to be falling in some countries

Northern Wheatears are now an every day sighting especially on the newly ploughed fields where they flit across feeding as they press ever northwards. These birds are one of the true long distance migrants and some have a very long way to go before they reach their breeding sites in the north

Looking for it's parents, a newly fledged Common Stonechat waits for food

Siskins aren't an abundant bird that I'd normally see on migration, but they do winter in some southern European areas and in north and west of Africa. This particular little finch was seen at La Linea, opposite Gibraltar suggesting that he'd just arrived back from across The Strait


Woodchat Shrikes have also been increasing in numbers over the past few days

Flocks of Calandra Larks can be seen around La Janda and across country where there are large open spaces

This Calandra was nesting on the edge of the Barabte Marismas last year

More splashes of colour this week from our stunning Iberian race of Yellow Wagtails. This male had difficulty with the wind this week and despite the strong Levante, we've seen hundreds pouring into the county from Morocco

Great Egrets are more numerous each year and I'll need to see if I can find a nest site this year

Taken this week during the high winds were a couple of shots of migrating Hoopoes that land exhausted and catch breath after a marathon crossing from Africa. They start off way up The Strait opposite Gibraltar and end up in Barbate, crabbing all the way down The Strait before they can finally make landfall

Exotic looking birds and quite a unique species

Preparing the rice-fields for planting. This is some of the dust that's been irritating my tired eyes the last week or so...

Red-legged Partridge spring plumage is just wonderful

And finally. I was really chuffed to see that Birdwatch has written this review in 'Best of the Blogs'. Thanks Birdwatch!
