What do Peregrine Falcons eat? It might be easier to ask what don’t they eat? Here’s a list of kills reported based on avian remains and feathers at the foot of the tall buildings frequented by the Cambridge Peregrines:

Bar-tailed Godwit, Blackbird, Black-tailed Godwit, Carrion Crow, Collared Dove, Feral Pigeon (Stock Dove), Fieldfare, Golden Plover, Great Spotted Woodpecker, Great Tit, Grey Partridge, House Sparrow, Moorhen, Redwing, Robin, Shoveller Duck, Starling, Teal, Woodcock.

The Peregrine Falcon (Falco peregrinus) is the world’s fastest animal. It stoops on its prey from way above and has been recorded as reaching speeds of an incredible 300 kilometres per hour. It basically slams into its prey to kill it and carries it off to a perch where it will pluck the bird before eating. It will also cache chunks of prey on tall buildings around its territory to eat later or for feeding nesting partner, and later chicks.

UPDATE: Breeding season 2023. In 2022, I mentioned the hope and possibility of Glossies breeding in the UK. This happened in 2023.

I’ve mentioned the Glossy Ibis many times before, there are still several in and around our local patch and almost 200 estimated to be across the British Isles. There were just four at a place where I’ve seen seven recently, but that’s fine. Four is better than zero.

They were all looking rather glossy, which is presumably in time for the breeding season. Whether or not these birds actually breed here is another matter. There is a breeding colony in Spain, but this African/Mediterranean species has been extending its range and hanging around the British Isles recently, but no reports of breeding or attempts at breeding just yet.

Maybe 2022 could be the year for it! Certainly, other recent acquisitions like Cattle, Great White, and Little Egret are in on the act.

I’ve talked about the Common, or Eurasian, Crane on the Sciencebase site before, there are increasing numbers of this bird to be seen on our East Anglian patch, and that’s a very positive, natural thing.

There is something quite primaeval about the species. Snapped here with a 600mm Sigma zoom on 2/3 crop sensor Canon 7Dii from about 370 metres. I didn’t know ahead of the visit that they were even there and snapped them when I saw them and left them to their own devices.

UPDATE: October 2023. Despite recent heavy rains the patch of farmland, on which birders (Ian and Brendan) had ticked 160+ species, has remained unflooded so far this season. I suspect the drainage along the fields and/or the adjacent travellers’ site have been fixed. So, it was fun while it lasted and maybe it will happen again, but it seems that for the timebeing we are not going to have quite the birding on that patch as we did last winter and the previous couple of seasons, unfortunately. So much for creating a protected birdlife area.

Over the last year or more (2020-2022), a patch of farmland known, as Bullock’s Haste, which lies on the outskirts of our village has been perpetually flooded. Incredibly, over two winters it has attracted a greater and greater diversity of bird species who have spent time there feeding, preening, and roosting.

Two friends dedicated to the citizen science cause of birding (Brendan Doe and Ian Ellis) have observed and catalogued (on eBird) more than 150 species there in that time. I cannot claim to have seen even a fraction of that number there, although I have seen a good many of the “ticked” species in various other places and several of them at this site. There are a few other named spotters on the list who have ticked several species, but Doe and Ellis have done the bulk of this excellent work.

Here’s the list as it stands, in alphabetical order. I have removed terms such as Eurasian, European, Northern, and Western from these vernacular names to simplify things.

UPDATE: 11 April 2022 – Little Gull has turned up

We ate the Spoonbill to extinction in the British Isles in the 17thC. But re-creating lost habitat, conservation work, and a reintroduction scheme is seeing their numbers crawling back.

North Norfolk is a good place to see them these days, but they’re also spreading their wings. Four have been present on one of our fenland nature reserves for weeks now, we saw them on a dull day back in the middle of winter. Kingfisher’s Bridge Nature Reserve.

Out of covid isolation at last, I thought I’d pay them another visit and was told by a birder (might have been a warden) that they weren’t around right now. Ten minutes later, two flew off the main lake and right over my head.

We do like to be beside the seaside, especially the North Norfolk seaside. We took the opportunity for a couple of days of long walks there. Sad that our pooch is no longer with us, but it meant we managed almost 20 miles of tramping over two days.

We did attempt to spot the juvenile White-tailed (Sea) Eagle that is jaunting between Cley and Stiffkey at the moment. It is a released bird from the Isle of Wight reintroduction scheme.

Regular readers will know I’ve mentioned the Glossy Ibises that have seemingly taken up residence on our patch during the last year or more. There were three on the flooded farmland adjacent to Earith roundabout for a long time last winter. These are African/Mediterranean birds that seem to be spreading their wings more and more (see also Great White Egret, Little Egret, Cattle Egret). The Glossies we’re seeing here may well be hopping across from a breeding colony in Southern Spain, while the GWEs may be feeding on red crayfish in the lakes of northern France and then hopping across The Channel.

Anyway, there are now seven Glossies feeding and preening at RSPB Berry Fen just up the road from Earith. Happily, they were “showing well” from the footpaths in the sunshine today. I did a bit of photographic enhancement of this shot to show how the natural colours might show given even brighter African sunlight.

Paid just our second visit of the year to Lackford Lakes Nature Reserve in the hope of seeing the Siskins that had been reported there this week. We stopped off at the ringing hut where two of the Suffolk Wildlife Trust team had netted various birds (Treecreeper, Blue, Great and Marsh Tits, Great Spotted Woodpecker, Robin, and others) and were carefully recording the recatches and ringing any new catches for their conservation efforts.

So, what did we see on the day? 46 species not in order of sighting but loosely grouped:

A Cattle Egret (Bubulcus ibis) flew into Berry Fen when we visited a couple of days ago to settle among the eight Little Egrets feeding there. In so doing it spooked two of the six Glossy Ibis that were feeding on the edge of a flooded area and they flew off to join four others of that species.

Apparently, there were fifteen additional Cattle Egret in a flock on the same patch the day after we visited, which is the largest recorded gathering of this species in Cambridgeshire. A county record, in other words. The bird is ostensibly an African species that has been extending its range over the last decade or two because of habitat opportunity and climate change.

UPDATE: There were a record 57 Cattle Egret at this site at the beginning of November. I have also now seen four at RSPB Ouse Fen on the Reedbed Trail side close to Over.

UPDATE: Four Spoonbills at Kingfisher Bridge Nature Reserve during November 2021. 15 February 2022: Spoonbill at Smithy Fen.

Back in the early 1990s when we visited Botswana and Zimbabwe we saw lots of egrets and then were very surprised to see one or two on the North Norfolk coast in subsequent years. Little Egrets are, almost 30 years later rather commonplace. Similarly, the Great White Egret is seen in many parts now and a sighting is no longer considered particularly notable. I heard that part of the reason is that there is an abundance of red swamp crayfish in the lakes of northern France which have provided a food source and hopping off point for this species. The presence of at least a couple of dozen Glossy Ibis on our patch during the last year or so, may similarly be due to individuals spreading their wings from a known breeding colony in Southern Spain. The experts may know more, but I don’t think anyone knows for sure.
