The Bearded Reedling used to be known as the Bearded Tit. The name change wasn’t down to some odd political stance. After all, the Great Tit, Blue Tit, Long-tailed Tit, and even the Penduline Tit are all still tits.

No, the rationale for the rename is that the Beardie is not a tit all. It may have some of the charactertistics of the Long-tailed Tit, well, basically a long tail, but those are purely superficial similarities. The Beardie doesn’t fit into the tit family.

The Beardie is not in any genus in which the proper tits sit. In fact, the Bearded Reedling, Panurus biarmicus, (sometimes known as the Bearded Parrotbill) is the only known extant species within the Panurus genus. There are likely to have been others in the past, but those are extinct, not extant.

The British Trust for Ornithology, BTO, says 695 breeding pairs in UK. RSPB website says 630, although it said that back in 2018 when I wrote about the species back then. I don’t think their data are updated often enough, estimates on counts have presumably changed in that time.

Another heron at RSPB Ouse Fen (Earith). There were 4 or 5 flying around. This is the Great White Egret, Ardea alba. It’s about the size of a Grey Heron, but white.

Quite a rarity in the UK, until maybe about 10 years ago, but like Little Egret, Cattle Egret, Glossy Ibis, and various other herons, it’s becoming an almost everyday sight in these here parts. I’ve seen perhaps 6 or 7 on the same patch at a different reserve, where there were also dozens of Little Egret and numerous Grey Heron. The GWE is not quite as common as the Little Egret now, but was removed from the “mega” list quite some time ago. It is far more common than the Purple Heron I mentioned recently.

Great White Egret is ostensibly an African/Mediterranean bird like those others. However, the species has been extending its range into Europe and the UK in recent years. Nudged by climate change, perhaps the main driving force is the presence of lots of crayfish in lakes in northern France that have given it a food source and the potential to hop across the channel. Once here, they find the old East Anglian gravel pits that are now full of water and marked as nature reserves a perfect home from home, it seems. Fairly common on the Somerset Levels these days too.

Back in June, we enjoyed seeing a lot of birds, butterflies, and moths in Greece. Many, if not most, of those were species rarely, if ever, seen in the UK. One bird we had a shout out from our skipper on Lake Kerkini was the Purple Heron, Ardea purpurea. I must confess I wasn’t quick enough to get a photo on the boat trip and not entirely sure I actually saw it among the Squacco and Night Herons that were in the reed as we rippled past.

Anyway, I was out looking for Bearded Reedlings at RSPB Ouse Fen (Earith), there were lots. A Bittern came up from the reeds briefly and ducked back down, as they do. There were also four Great White Egrets flying about. But, it was the odd-looking heron in the distance that was the most intriguing…it definitely wasn’t another Bittern, but didn’t look quite right for a Grey Heron.

When I got back to base camp, I checked the photos. It was obvious on zooming in on the photo Purple Heron, Ardea purpurea. Juvenile. The species is smaller and more slender than the Grey Heron, markings are different, and overall it has darker plumage. The species is more commonly found in Africa, central and southern Europe. However, juveniles do occasionally spread their wings from the near Continent between August and October and end up in East Anglia and beyond. Sighting now with the County Bird Recorder, Jon Heath.

Mrs Sciencebase remembered there had been reports of that species earlier in the year locally. I checked on Birdguides and she was right, there had been one here back in the summer of 2023 and a scattering of others over the last few years. Indeed, earliest Birdguides record I can see on the app is summer 2003 at Needingworth (which is now part of RSPB Ouse Fen).

Looking at the national sightings on the app, I can see sightings of Purple Heron in Somerset, Shropshire, Norfolk, Devon, Suffolk, Jersey during September and October.

This is one of my natural highlights of 2024. I will give you a full update of those on New Year’s Eve!

There are several species of parakeet present in European cities alongside the Rose-ringed, or Ring-necked, Parakeet, Psittacula krameri, also known as the Kramer Parrot. The others are Blue-crowned Parakeet, Thectocercus acuticaudatus, the Alexandrine Parakeet, P. eupatria, and the Monk Parakeet, Myiopsitta monachus. If we’re talking parrots in general, there’s also the Common Parakeet, perhaps better known as the Budgerigar, Melopsittacus undulatus.

The Rose-ringed Parakeet is well known in city parks and green spaces with trees across Europe from Athens to Amsterdam, Barcelona to Bonn, and Lisbon to London, and even as far north as Newcastle. The common sub-species in those cities is native to Africa but has adapted successfully to living in disturbed and urban habitats having escaped deforestation. Their presence in London has nothing to do with an imagined publicity stunt by Jimi Hendrix.

Rose-ringed Parakeets were and presumably still are a popular pet bird species and so escapees have fed into the feral populations. It is naturalised in many places now, breeding as if native. But, it is considered a pest in places where the sub-species in India has bred into massive colonies, but in Europe there does not seem to be a need to cull them. Peregrines, Hobbies, and Tawny Owls will all predate Rose-ringed.

Meanwhile, the Blue-crowned Parakeet is a native of South America. It is generally found from eastern Colombia to Curaçao in the southern Caribbean to the northern parts of Argentina. It prefers savanna-like habitats, woodland, and forest margins and so is generally not present in dense, humid forest like the Amazon. Introduced, as one might expect, to the USA, specifically south Florida, California, and Hawaii. It is now present in several cities across Europe too, Barcelona, Lisbon, Milan, Paris, Zürich, and on the Canary Islands.

A Blue-crowned Parakeet nest with eggs, subsequently predated, was observed in 2001 in Lewisham, southeast London.

We spent a few days in Lisbon in early October, our first time in the beautiful and cosmopolitan capital of Portugal. Man, it was nominally a city break to celebrate our 32nd wedding anniversary, which was earlier in the year. There had been the notion of perhaps heading up to the Tagus Estuary Nature Reserve to see the flamingos, but we didn’t get there in the end. We kept our eyes peeled for birds in between more conventional city sightseeing in the city, as well as Belém (west along the river) and Oriente (to the east, as the name would suggest).

We didn’t spot any Black Kites, Azure-winged Magpies, nor Hoopoe, which I’d hoped for, but there were lots of Crested Myna, Black Redstart, and Rose-ringed Parakeets at the Mosteiro de Jeronimos in Belém. A couple of hours at the Parque Eduardo VII added Sardinian Warbler, Short-toed Treecreeper, and Serin to the list. Then another couple of hours in the Botanic Gardens added two species of parakeet Blue-crowned and Rose-ringed.

It was wonderful to spend some time in the peace of the Lisbon Botanical Gardens away from the bustle of the streets and the trams. It was also warm and sunny while we were there and with the sight and sound of Willow Warbler and Blackcap around it was almost like a summer rewind. The deciduous trees were starting to show signs of the autumn, of course, but it was still 25 Celsius and very humid, twice the temperature it had been at home when we left Old Blighty.

We finally caught up with a load of European Serin, Serinus serinus, in the Edward VII park in Lisbon. Not seen this bird species before, it’s related to the Ethiopian Siskin and the Black-headed Canary, but you could also say it’s a distant cousin of the European Goldfinch and the European Siskin, to which is bears more than a passing resemblance. They’re all finches, basically.

The hopefully complete bird list for our four-day ostensibly non-birding trip. Birds without a place were seen in various places or just around Lisbon/riverside in general. Birds marked * are lifers for us.

Just to add, we saw a few Large White butterflies, presumed Speckled Wood, and a few Lang’s Short-tailed Blue, and also Velvet Carpenter Bee, and some fish in the river, but, that was pretty much it on other wildlife, as you’d expect from a city break.
