Survey Results

Here you can read summaries of survey data. These are analyses of our online surveys whenever possible, targeted species surveys, and previous community bird surveys (from 2000 and 2005).  We'll update this page with the latest results every few months. Survey results from 2000-2008 can be found at the links on the bottom of this page.

December 2016

Earlier we talked about the relationships between bird species and the habitat features they like. However we have also found some interesting statistically significant relationships between some of our most common bird species and a whole range of less common birds – some good, some not so good!

 

Gardens with Noisy Miners were less likely to have some other native birds in them including small birds like the Superb Fairy-wren, Eastern Yellow Robin, White-plumed Honeyeater and Double-barred Finch, but also Yellow-tailed Black-Cockatoos. It is possible that this was the result of a direct interaction (so Noisy Miners chasing away other birds, as they are often observed doing) but it could, in some cases, also be due to these birds liking different types of gardens (with Noisy Miners liking tall trees and open lawn)

 

On the other hand, the Common or Indian Myna had a mixed relationship with other birds. They had a negative relationship with only three other species that we could detect – the Common Bronzewing, Brown Thornbill and Double-barred Finch. However they had a positive relationship with other ground-foraging birds like Willie Wagtails and Australian Magpies. A really interesting result and something that warrants more investigation! Keep sending us sightings to the Backyard Bird surveys so we can explore these relationships.

 

A reminder too – work is underway to move our Backyard Bird surveys on to the fantastic new BirdLife Conservation Portal. You can get a head start by registering on the site so you are ready to go when the portal is. Please remember to use the same email address as you have for Birds in Backyards so we can sync up your records.

 

 

October 2016

Whilst the Aussie Backyard Bird Count takes a yearly snapshot of the birds that live where we live. Our Backyard Bird Surveys are available year round and take a closer look at our gardens, what features our birds are attracted to and the relationships between different bird species. So what are your surveys telling us about what sort of plants we should use in our gardens?

 

Most native species were more commonly seen in gardens with mostly native plants including native trees (this included species like Eastern Spinebills, Superb Fairy-wrens and Crimson Rosellas). For many of these birds no trees are preferable to the presence or dominance of exotic tree types. Introduced birds such as House Sparrows and Common Myna show a preference to sites with mostly exotic tree types, however the introduced Spotted Dove seems to prefer a native tree canopy. Spotted Doves and Common Mynas were also likely to be found in gardens with no trees at all. These are birds that like being on the ground or hanging around our houses.

 

So the old adage that native birds prefer native plants is definitely showing through here - so even by getting some sort of native plant of tree in the ground you are helping many native birds, whilst creating a garden that is less attractive to introduced ones - it's a win/win! Check out your local nurseries and find some that are locally native to your region.

 

 

August 2016

The data you send in to us from the Backyard Bird surveys is invaluable. We are learning so much about what many of our native birds are looking for in our backyards. Lets have a look at another suite of species – some honeyeaters:

 

Noisy Miners

  • Many of you know these birds well. They are extremely territorial and do not like sharing their space with any other birds. They are thought to be one part of the reason for the decline of small native birds like spinebills and wrens.
  • The characteristics of an individual garden probably gets swamped in a Noisy Miner territory (because they occupy so many) and it is likely that instead, it is the composition of a number of gardens that influences them, but…
  • They were statistically less common in gardens with more than 50% of shrubs – so get planting!
  • You found them more often in gardens with a lot of trees (more than 50%) – so if you have a great tree canopy, it becomes even more important to have that dense shrubby understory underneath
  • They were more often found in gardens where there were not dogs, but more common in gardens with aviary birds
  • Gardens were bread was provided daily, or meat was provided daily or infrequently (monthly) had Noisy Miners more often.

 

Little Wattlebirds

  • Definitely more common in native gardens or those with an equal mix of native and exotic plants
  • Showed a clear preference for lots of native shrubs, but less than 50% tree cover
  • They were twice as common in gardens with a dog that without!

 

Brown Honeyeaters

  • These little birds became less common the further gardens were away from bushland
  • Definitely preferred gardens with lots of small plants in them but strangely enough, also either lots of trees or none at all! It is likely that in the absence of trees they were looking for other dense layers of vegetation.

 

Some of these results may seem a bit confusing, but there are some clear messages. Shrubs are so important for so many of our birds – both to encourage some, and discourage others. Likewise, being close to, or connected to a patch of bush is vital. Birds move around the landscape using our gardens as stepping stones – so by adding your bit, especially if you are further away from bushland, is so important.

 

Your favourite honeyeater might not have been mentioned – these were only the birds that showed us statistically significant results. So it might be that either 1. They don’t have any preferences in gardens or 2. We don’t have enough data on them yet.

 

So keep sending us through your surveys – as you can see, they are giving us some really important information but the more we get the more we are learn.

Don’t forget, once we move to the new BirdLife Conservation Portal, you will need a new log in to submit surveys. You can get prepared by setting up this log in now. Visit Birdata here.

 

 

June 2016

We’ve been doing some digging into the past 10 years of Backyard Bird surveys and are uncovering some great information about the types of gardens that attract certain bird species using statistical analyses – all based on the surveys you send us. Here are some findings for just a few of the parrots:

 

Eastern Rosella’s preferred:

  • Gardens that were between 50m to 5km away from bushland rather than those right next to or greater than 5km away.
  • They were most common in gardens with between 25-50% shrubs but least common in gardens with more than 50% shrubs.
  • A lot of lawn (>50%) rather than less lawn.
  • The composition of the plants and trees (native or exotic) didn’t matter.
  • Strangely, they were more common in gardens with dogs and pet birds! This doesn’t necessarily mean that these animals are attracting them per se, but some feature related to the pets might be creating a good habitat for the rosella’s.

 

Rainbow Lorikeets were in gardens that:

  • Either had no trees at all, mostly native or an equal mix of natives and exotics. They were much less common in gardens with mostly exotic tree species.
  • Had a lot of small plants but also more than 25% hard surfaces.
  • Unsurprisingly they preferred gardens in which sugar (nectar/honey) was provided daily or weekly.

 

Yellow-tailed Black-Cockatoos preferred:

  • Gardens that were closer to bushland. They were least likely in gardens between 2km and 5km from bush.
  • Gardens that didn’t have less than 25% shrubs.
  • Water only being provided infrequently (weekly or monthly) or not at all.

 

Stay tuned for more results as we work through habitat preferences for many more species. Please keep sending through your data. One thing that is clear is that regular surveys really help! So any time you can send us in a quick survey we would really appreciate it.

 

December 2015

 

Whilst the Aussie Backyard Bird Count is a one-off event each year, we do have our Backyard Bird surveys ongoing. This year saw a temporary change to the surveys and next year we will be moving them to the fantastic BirdLife Australia Conservation Portal (I will let you all know when that happens). So lets take a look at the findings from 2015…

We have had 1177 surveys submitted to us from around the country (from January till the 7th of December). Thank you for those who did a 20 min count, a weekly tally or told us what they have seen throughout the year. Here are a few highlights:

 

The 20 min surveys are the most popular surveys submitted (81%)

 

There were an average of:

  • 8 species seen in a 20 min survey

  • 27 species seen in a weekly tally and

  • 31 species seen in a yearly count

The maximum number of species recorded was a huge 74 during a week list!

Most surveys:

  • Were submitted from NSW

  • Were between 50m and 2km of a patch of bush land (61% of surveys)

  • Had an equal mix of native and exotic plants (56%) but a mostly native tree canopy (81%)

  • Had only none or only small amount of hard surfaces (94%), lawn (50%) and small plants (82%)(totaling less than 25% cover of each)

  • Had a large proportion (45%) of shrub cover (classified as 50% cover) but 30% of surveys were in areas with no shrub cover at all.

  • Had some tree cover (only 8% had no trees), with most having a few to some trees present (78%) (classified as <25% to 50% tree cover).

  • Provided water daily for birds (66%)

 

Check out below for the top 20 birds recorded this year. It is quite a bit different to the Aussie Backyard Bird Count!

Most birds (particularly those most commonly seen) are your typical big, bossy urban birds, but it is great to see smaller birds like the Brown Honeyeater and Willie Wagtail showing up in almost 1 in 4 surveys and only one introduced bird (the Spotted Dove) making an appearance in the top 20.

 

Lets get planting and get some of the smaller native species climbing the ranks and appearing more commonly in our Backyard Bird surveys in 2016!
