Irish Garden Birds - Rambunctious Redpolls

We're past the halfway point of this winters Irish Garden Bird Survey - this is the time of year when bird numbers and diversity tend to increase in gardens, as the weather gets a bit colder and the natural food sources in the wider countryside are depleted. Remember to keep feeding your garden birds, and water is important too. And lastly, be sure to give your feeders and water dishes a regular clean to ensure your birds stay healthy!

This edition of the blog is a classic 'January' species in the Irish Garden Bird Survey - the Lesser Redpoll!

...............................................................................................................................

Species Profile: Lesser Redpoll

As Gaeilge: ‘DeargĂ©adan’
Irish Garden Bird Survey Ranking 2017/18: 27th place
Conservation status: Green-listed in Ireland and 'secure' at European level.


Lesser Redpoll (Kevin Murphy)

Did You know?

  1. The most common species of Redpoll in Ireland is the Lesser Redpoll - which has only recently been recognised as a seperate species to the Common (or Mealy) Redpoll, which is a bit larger and paler. Common/Mealy Redpolls occur here in small numbers in the winter, and there are also occasional sightings of the even more pale Arctic Redpoll! 
  2. Lesser Redpolls are a small species of finch - only slightly bigger than a Blue Tit. They have tiny beaks that are adapted to feed on very fine seeds. They often associate, or even flock with, other fine-seeding-eating finch species; namely Goldfinches and Siskins. So if you've had a flock of Goldfinches visiting your garden this winter, it's worth keeping an eye on them at this stage of the winter to see if they've brought some of their smaller cousins along with them! 
  3. ID-wise, the red isn't always obvious - particularly on the females, but if you're seeing a small brown streaked finch in your garden then chances are you're looking at a Lesser Redpoll.
  4. In the summer they breed in young conifer plantations and scrubby woodland that you might find down country lanes and boggy areas - keep an ear out for their call as they fly overhead! 
  5. They're a widespread breeder across the country now, but believe it or not breeding in Ireland was only first recorded in Co. Kerry in 1910.

How long do they live?

The oldest known Lesser Redpoll in Ireland and Britain was 6 years, 10 months and 11 days old.. Their typical lifespan is around 2 years however.

What do they feed on? 

Lesser Redpolls are small and have very fine bills, which means they're perfectly adapted to hanging from very small branches and eating the seeds and cones of Birch, Alder, Larch and other young conifer trees. As these food sources get depleted over the winter, they'll move into gardens - favouring Nyger Seed whether in a feeder or scattered on a bird table. They will eat from peanut feeders too.

Irish Garden Bird Survey Trends:

Looking at the last 20 years of Irish Garden Bird Survey results, Lesser Redpolls were only recorded in less than 20% of gardens in the late 1990's and early 2000's, but made significant gains over the last 15 years or so to eventually be recorded in over 40% of gardens in 2011/12, 2012/13 and 2015/16.

Last year they were recorded in 35% of gardens, and on average over the last 20 years they are seen in around 30% of gardens each winter. That means they generally come in the top 30 birds in Irish gardens each year, and occasionally making it into the top 25. Cold winters, poor seed crops in their preferred conifer trees, and good breeding seasons are all causes for their particularly high numbers in gardens in some winters!

Movements and Migration:

There is some movement of our Lesser Redpolls between the summer and the winter. First of all, birds flock outside the breeding season so they will roam around the countryside throughout the autumn and winter. Many of our birds stay in Ireland, but some move to the UK in the autumn. Five Lesser Redpoll ringed at our East Coast Nature Reserve in Wicklow in September 2006 were retrapped over the following winter and spring in various parts of the UK, while another turned up in Belgium in 2008! Depending on the severity and the quality of the autumn seed crop they may be forced to move to central Europe during some winters. Similarly, birds from Scandinavia facing the same pressures are occasionally forced down into the UK and Ireland too.

How can I help Lesser Redpolls?

Because of their very specific breeding habitats, Lesser Redpolls aren't the type of bird that will take to a nestbox in your garden. They are a very small bird however, so putting out food for them in the winter will help increase their survival rates and ensure they make it to the next breeding season alive and well and in good condition! With that in mind, Nyger Seed is the best thing to put out for them - either in feeders, or scattered on a bird table. Keep an eye out for them throughout January, February and even March - if a few birds find your feeders they'll probably bring more and more friends as the weeks go on!

Irish Garden Birds - Humble House Sparrows

We're near the midpoint of this years Irish Garden Bird Survey now. It's been mild until late, but as temperatures drop and food runs out in the wider countryside you can expect greater numbers and diversity of species to be visiting your garden in the coming weeks.


This weeks species profile is the humble House Sparrow! Some people don't get these birds in their garden at all, but if you do they're probably there in good numbers!




..............................................................................................................




Species Profile: House Sparrow

As Gaeilge: ‘Gealbhan binne’
Irish Garden Bird Survey Ranking 2017/18: 9th place
Conservation status: Amber-listed in Ireland due to declines at European level.

Did You know?
  1. The House Sparrow is one of the most widely distributed birds in the world. It is native to Europe and much of Asia, but was introduced by humans to Australia, parts of Africa and the Americas too.
  2. House Sparrows are very social birds. In summer they nest in close association with other pairs. You can buy special 'terraced' nestboxes to accommodate them. In winter they flock together.
  3. House Sparrows are predominantly seed-eaters. Over the centuries they came to realise that there is often seed available around farm buildings and dwellings, leading to a close association with humans and the 'house' in their name. Their association with humans is thought to date back around 10,000 years
  4. Recent research has shown the species has declined drastically in many urban areas - thought to be linked to air pollution and poor diet. See here for more details.
  5. House Sparrows can fly at around 45km per hour.

How long do they live?
The oldest known House Sparrow in Ireland and Britain was a bit over 12 years old, but on average they only live around 3 years - similar to a lot of our garden bird species. 




What do they feed on? 
House Sparrows are predominantly seed-eaters, but will often eat various scraps from the garden, as well as peanuts. During the summer they will eat some insects, particularly when feeding their chicks.

Irish Garden Bird Survey Trends:
Over the last 20 years of the Irish garden bird survey, House Sparrows have drifted between 7th and 12th place, coming in around 10th place on average. That means that around 82% of Irish gardens have recorded House Sparrows in the last 20 years. They seem to be doing slightly better in recent years, which fits in with their 'moderate increase' status as seen during the summer via the Countryside Bird Survey'.



Numbers don't really vary much over the winter, with gardens getting an average of 6-7 birds each week.





The graph above shows the percentage of gardens in which House Sparrows have been recorded - occurrence has increased slightly in recent years to around 85%.


Movements and Migration:

House Sparrows are largely sedentary and there have been few if any recoveries of House Sparrows ringed in Ireland being recorded abroad, or vice versa. In fact, House Sparrows usually winter within around 20km of where they breed or were born, so those ones in your garden probably aren't from too far away.


For the 15-20% of gardens who don't get House Sparrows in the winter, this is probably because you don't have them nesting nearby. 


How can I help House Sparrows?
The best way you can help House Sparrows is to provide them with additional nesting space via a nestbox. House Sparrows like to nest near each other, so if you have House Sparrows either visiting or already nesting in your garden then you can put out a few nestboxes on the same wall for them. Alternatively, you can buy a 'terraced' nestbox for them from our BirdWatch Ireland shop, which is essentially three nesting compartments in one box. 

A terraced nestbox like this, with three nest compartments, is available to buy in the BirdWatch Ireland shop. 






In older houses, House Sparrows can nest in the eaves and guttering. If you'd rather they didn't, then block up the hole outside the breeding season (i.e. now!) and put up some nestboxes to give them an easy alternative to nest in!

When it comes to putting out food for House Sparrows, peanuts and seeds are the way to go!
