Lesser Redpoll

Irish Name: Deargéadan
Scientific name: Carduelis flammea cabaret
Bird Family: Finches
green
Conservation status

Status

Widespread breeding species mainly in upland areas.

Identification

A small, acrobatic finch, with short forked tail, upperparts streaked brown, paler below. Adult males have a reddish forehead, and neat black bib, with small, bright yellow bill. In summer, males have a reddish flush to the breast. Juveniles and females are duller, lacking the red on the breast. Often forms mixed flocks with Siskins, its movements reflect availability of food supply.

Voice

A distinctive “chet-chet-chet”, which is frequently used in flight. Also a “pyu” given when alarmed. The song consists of the main call interspersed with a buzzing “zrrrrr”.

Diet

Feeds on a variety of tree seeds, willow, birch, alder and larch are favoured. Will also forage grass and weed seeds, stubbles etc., and has taken to winter feeding on peanut feeders in gardens.

Breeding

Redpolls breed in conifer plantations in upland areas.

Wintering

Redpolls disperse out of their breeding areas to winter in lowland areas usually in small flocks. Favours stands of Ash and Birch, where it uses its fine bill to extract seeds. Increasingly visits suburban bird feeders, especially in late winter, when natural food supplies are running low.

'Last Christmas' - Birds in Irish Gardens last winter

There's still time to take part in the Irish Garden Bird Survey!! See here for more details. 

  If you’re a BirdWatch Ireland member you’ll have already read the results of last year’s survey in your winter edition of Wings magazine. If you’re not a member, please join and support our work! But you can catch up on last year’s Irish Garden Bird Survey results with the overview below. If this is your first year to take part in the survey, don’t worry about knowing every single species that might appear in your garden – just familiarise yourself with the most common ones to start off. If you’re a survey veteran, then see how your garden bird list compares to the national average!    

Over 90% of Irish Gardens

The species at the top of the list didn’t change much from previous years. Robin, as per usual, was on top, followed by Blackbird and Blue Tit. Great Tit and Magpie moved up a place each into 4th and 5th, thanks to a fall in the numbers of Chaffinch reported. Robins can still be territorial in the winter, so are pretty evenly spread across the country, while our Blackbird population is topped up by hundreds of thousands of migrants from Scandinavia in the winter, hence their high-ranking each year. Blue Tits and Great Tits are pretty ubiquitous too, and Magpies are very effective at exploiting both urban and rural habitats.  

 

80-90% of Irish Gardens

Chaffinch and Goldfinch fell two and three places to 6th and 10th respectively, since the previous winter, and those declines were greatest in urban and suburban gardens rather than rural ones. On the back of a great breeding season, Coal Tit moved up three places to 7th place. House Sparrows kept 8th position, and Starling made it into the top 10 garden birds for the first time in a decade!  

 

50-80% of Irish Gardens

Wren dropped two places to 11th, while species such as Dunnock (12th), Rook (16th), Collared Dove (17th) all stayed in the same position as the previous winter. When a winter is pretty mild (the occasional storm excluded) we tend to see this stability in the rankings across many species. There was some slight movement for Woodpigeon (14th), Jackdaw (15th) and Hooded Crow (19th), all of which fell one place. The mild weather tends to mean these species aren’t forced to retreat to gardens for food as much as in other winters. Song Thrush increased by around 2% and jumped to places in the rankings to 13th. Pied Wagtail rose up two places to 18th and occurred in >7% more gardens than they did on average over the preceding five year period. Despite being very common in towns, cities and shopping centre carparks, they’re actually seen in twice as many rural gardens as urban or suburban ones. Greenfinch continue to suffer the devastating effects of trichomoniasis (make sure to clean your feeders regularly!) and reached a new low for the species in the survey – 20th place.   Pied Wagtail

 

20-50% of Irish Gardens

While the above species occur in more than 50% of gardens, you’re in the minority if one of the below appears in your garden this winter: Siskin jumped up 7 places (8%) since the previous year. They usually start to appear in gardens from mid-January onwards, but they were making appearances from late November right through to March in most parts of the country last winter. No other species made such a big jump pup the table! One of the bigger losers was Goldcrest - down 5 places to 29th, a decrease of nearly 8%. It was a mild winter, and a good breeding season for most species in 2020, so the reason for this isn’t immediately obvious. Bullfinch dropped three places to 24th, but this might just be due to the mild winter and abundance of feeding options in the wider countryside, as they’re not a bird that visits feeders and so aren’t as associated with gardens as other finches. Other species in the 20-50% band include Blackcap, Long-tailed Tit, Sparrowhawk, Mistle Thrush and Feral Pigeon. Again, not species that tend to avail of bird feeders with any regularity, but species who know how to make a good living in a human-dominated landscape, be it rural, urban or suburban.

Best of the rest

Despite being a non-native species, Pheasants tend to be seen in 15-20% of gardens each year, which is surprisingly high considering they don’t tend to breed well in the wild, so are reliant on being released by gun clubs every autumn. Buzzards moved two places up the rankings and are seen over 15% of gardens each winter. Herring Gulls were in 11% of gardens, Black-headed Gulls in 4%, and 1.3% of gardens had some sort of gull visiting but weren’t sure what species! Great Spotted Woodpeckers are one of the most recent additions to our bird community, and over 4% of gardens had one visiting their peanut feeders (it’s always peanut feeders!) last winter. They’re now breeding in almost every county in Ireland, so expect to see them charging up the rankings table in the coming years. Last year was a mast year for acorns, which meant Oak trees were providing a huge bounty for species such as Jays, and as a result they were seen in fewer gardens than usual (8%, down 1% from the average). This tends to happen every few years. Lastly, Redwing and Fieldfare, our two wintering thrush species, both dropped a bit, thanks again to the mild winter.   jay-drinking-from-hollow-tree-trunk     See below for the full Top 30 birds in Irish gardens last winter, and their various ups and downs since the previous year. Most gardens record between 10 and 25 species over the course of a winter. Whether you have more or less than that, we still need you do to the survey!

Irish Garden Birds 2020 - How much do your garden birds weigh?

There's still time to get started with the Irish Garden Bird Survey!  It's the biggest and longest-running survey of it's kind in Ireland. We need as many people as possible all over the country to take part this winter. Taking part couldn't be easier - See here for details on how to participate this winter . See below for information on how much your garden birds weigh, and why feeding them at this time of year is so important! 

 

The Irish Garden Bird Survey is kindly sponsored by Ballymaloe. Click below to learn about taking part this winter.

  The birds in your garden are much more worried about putting on weight this Christmas than you are! If you have a small body, your surface-to-mass ratio is much higher, which means there's more of a surface area for your body heat to escape from - i.e. you can lose heat very quickly. Heat is energy, and if you’re losing heat and burning off more body fuel than you put on each day then you’re in trouble! This is why feeding your garden birds is so worthwhile – not only are you giving them food high in calories, fat and protein, but you’re providing a predictable source of food so they don’t have to waste energy every day traversing the hedgerows of the countryside in search of any morsels that might keep them going. The winter days are short and the nights are long and cold, so anything that saves the birds energy is a gamechanger!   To really hammer home the point it’s worth thinking about just how little our garden birds actually weigh. We know this through bird ringing. Trained and licensed scientists and ornithologists, in a largely voluntary capacity, catch birds and fit them with a small metal ring to get an idea of how many individuals are in an area, how long they live, how far they travel and a whole host of other data which is pooled together to help us learn about some of the intricate details of the lives of our common and rare bird species. One of the standard bits of information recorded during ringing is the weight of the bird. People occasionally email BirdWatch Ireland saying they saw a ‘big Blackbird’ or a ‘small Starling’, but in reality the variation between individuals of the same species is generally quite small (except where males and females are quite different e.g. corvids, pigeons,  birds of prey). See below to get an idea of how much your garden birds weigh, and how much of a difference a few grams of peanuts, seeds or fatballs make to their attempt to survive the winter! And remember, if you're buying bird food, feeders, nestboxes and other bird-related gifts this winter then check out the BirdWatch Ireland Shop here - by buying from us you're also helping to support our conservation work!     Traditionally, one might compare the weight of a small bird to that of a coin or a known amount of coins but given the likelihood that your wallet or purse has more plastic cards than coins in it, lets go with that. So, the average bank or supermarket clubcard weighs 5g – keep that in mind!  

Less than 10 grams (two bank cards)

The smallest bird in Ireland is the Goldcrest – they weigh a mere 6g on average but can range from 4.7g (i.e. less than your bank card!) to 6.1g. Not far behind them, with average weights of 9-10g are Long-tailed Tit, Coal Tit, Treecreeper and Wren. These species will be the most active in your garden over the winter because the days are so short that they literally need to be feeding non-stop throughout the day to maintain their weight and survive the night! Wrens and Long-tailed Tits, amongst others, are known to communally roost during the winter – that is, they find some sheltered location and squeeze in together for the night in an effort to share body heat! In the case of Long-tailed Tits, because they’re all closely related they will take turns in the middle (i.e. warmest part) of the group before moving to the outside to give someone else a turn. For other species, where a roost will comprise of a number of unrelated individuals, they’re less generous, so you don’t want to be the last one in and stuck on the outside of the group!  

10-20g (two to four bank cards)

Some individual Blue Tits and Lesser Redpolls might come in at under 10g, but generally they average around 11g and can range up to 12.5g on a good day! Siskins are only slightly bigger at 13g, and then you have Goldfinch (17g), Great Tit (18g) and Robin (19g). Robins play it smart by staying territorial in the winter, and even the females will guard a territory – sometimes one where there’s suitable food but a lack of nesting space so it wouldn’t have been a core territory during the summer. By identifying somewhere with a suitable food source and aggressively guarding it, they save themselves a lot of energy and trouble having to range far and wide in search of food. Goldfinches do the opposite by flocking, but the more eyes in a flock the more likely you are to find food.

20-30g (four to 6 bank cards, or 3 or 4 € coins)

Despite looking much chunkier and heavier, Bullfinches weigh the same on average as the slimline Pied Wagtail (both 21g), and our wintering Blackcaps are the same. Chaffinch weigh in at 24g on average, and it won’t surprise you that House Sparrow (27g) and Greenfinch (28g) are at the top end of the scale when it comes to ‘small’ garden birds. Still, as heavy as they might be, you’re still talking a few bank cards, or four €1 coins! When you think about the battle for survival that these birds face day in day out, it’s amazing that something so small and slight can achieve so much! Don't forget, in the case of the Chaffinch some of the birds in your garden will have migrated from as far away as Scandinavia, in the hope that their chances of finding food and surviving the winter are better here, even taking into account the pressures of migration. Tipping the Scales Of course, there are some much bigger species that use Irish gardens. Despite all looking roughly the same size, there’s a lot of variation in the Thrush family. Redwings, which migrate here from Iceland and Scandinavia each winter weigh around 63g, our resident (and some migratory..) Song Thrushes range from 64-90g but usually come in around 83g, Blackbirds and Fieldfares both average around 100g and Mistle Thrush is the real heavyweight of the family at 130g.   Once you start looking at bigger birds, there tend to be more of a difference between the sexes, with males generally bigger than females for the crows and pigeons. Amongst the crow species, Jays weigh the least (168g), followed by Magpies and Jackdaws (220g, 230g), then Rooks (450g) and Hooded Crow (510g). In the case of Magpies, males are around 40g heavier than females and for Rooks there’s a 60g difference, with the others showing similar discrepancies. For the pigeons, Collared Doves (205g) weigh around half as much as Woodpigeons (507g). Imagine being a 10g Coal Tit, plucking spilled seeds from under a bird feeder when a Woodpigeon more than 50 times your size lands beside you!
Collared Doves look only a bit smaller than Woodpigeons, but actually Woodpigeons weigh twice as much!
  Lastly there’s the exception to the rule of sexes. Amongst many birds of prey the female is actually bigger than the male, and it’s the same for Sparrowhawks. Females weigh on average 266g (range 186-345g), while males are a third smaller at 151g (range 131-180g). Such a big discrepancy between such specialist birds means that male and female Sparrowhawks will actually target very different-sized prey to each other.   male-sparrowhawk-perching-on-mossy-rock
Male Sparrowhawks are a third smaller than females.
  When you realise just how small most of our garden birds are, you can really appreciate the importance of a reliable food source for them, particularly during the winter! Remember, BirdWatch Ireland needs your support now more than ever, and our annual membership makes for a great christmas gift that will keep on giving throughout the year!
