The Great Maltese Bird Shoot

I went to the TV wildlife presenter Chris Packham's "iConserve Plus: A Brief Tour of my Phone Diary" talk recently. Going through the photos from 2016 on his phone, Chris told many amusing personal stories, and highlighted key conservation issues and debates. Having been born on Malta, the story that struck me most was the traditional bird shooting and trapping that takes place on this tiny island nation. Malta's traditional hunting season is in Spring when a number of protected bird species fly into Europe from Africa via Malta on their crucial migration route; a secondary shooting season takes place in Autumn when the birds fly back. Every year, 108,000 birds are killed illegally, placing Malta top on the list of highest concentration of birds killed per square kilometre in the Mediterranean (overall numbers are higher if you consider legal shooting as well!).

Birds from hundreds of species are shot in Malta, including swifts, Montague's harriers, kestrels, quails and the European turtle dove. The European turtle dove is particularly vulnerable: populations have fallen by up to nearly 50% in the last 16 years leading it to be put on the IUCN Red List of species at risk of extinction. The Maltese government has introduced quotas for number of turtle doves allowed to be shot in one season (5000 birds each Spring; 7000 birds each Autumn), but Birdlife Malta questions whether these quotas can be accurately stuck to, and many more turtle doves are shot illegally outside of these quotas.

The Federation for Hunting and Conservation Malta (FKNK), the Maltese hunter's association essentially, regard bird shooting as "Maltese indigenous socio-cultural way-of-life", and that to ban the hunting and capturing tradition "kills or rather murders an integral part of that individual". Indeed, reading some of FKNK reports, I find it striking how emotive the language is, and while I understand that hunting and trapping is steeped in Maltese tradition and deep-rooted personal identity, it's worrying how much this passion obscures willingness to accept the scale of problems associated with the practice. Shooting may have been acceptable in the past when the birds were a source of food, but nowadays it's simply all about the fun of the hunt. Regarding trapping of birds, the FKNK explain that birds are trapped for captivity; live-decoys (presumably to enable further hunting and trapping?), for "their song" (surely it's nicer to hear birds singing outside than cooped up in a cage?!) and for "captive breeding enthusiasts" (doesn't sound very official). Are any of these reasons really good enough for continued hunting and trapping of the wild migratory birds?

It's not just hunting and trapping either: in discussing the 2011 Trees and Woodlands Protection Regulations, the FKNK emphasizes how its members have transformed the arid Maltese "semi-desert" into "miniature oases" through the planting of indigenous trees such as olive and Aleppo pine as well as non-native Acacia and Eucalyptus. According to the FKNK, the Maltese and Gozitan countryside now "looks a great deal better than it did a generation ago", and they are offended that the Trees and Woodlands Protection Regulations will result in these trees being cut down again. But this is it, the Regulations aim to preserve Maltese woodland communities and particularly endangered, threatened or endemic flora and fauna species. The regulations specifically mark Acacia and Eucalyptus in the "invasive, alien or environmentally-incompatible species" category as they are not compatible with these aims of protection. The FKNK report doesn't seem to understand this however, as it goes on about, for example, how Accia Karroo (the FKNK made a mistake there as it should be Accia karroo- you should only ever capitalise the genus, not the species!) is "one of the most beautiful and useful trees", and gives information about the tree that is irrelevant to the Maltese context. The tree may be beautiful, but it is an invasive species, thus impacts the stability and biodiversity of the native ecosystem, and can reduce ecosystem service delivery. The FKNK has the word "conservation" in their official name but that seems to just be a formality to make them seem more eco-concerned than they are- they seem quite ignorant on ecology and hunting impacts.

Birdlife Malta is active in opposing the Spring and Autumn shoots. The organization is critical of the Maltese government's lack of action in safeguarding migratory birds, pressures the Maltese government to suspend the hunting season to allow safe passage for migratory birds; reports illegal hunting to the police and Wild Birds Regulation Unit (WBRU); watches over key hunting areas even when hunters react violently; tends to injured birds; and educates the public through environmental education programmes and training of environmental youth leaders who engage children and the public with wildlife.

Overall, I've always supported communities keeping up old traditions and being proud of their heritage, but this hunting and trapping seems to be nothing more than an outdated practice at odds with the bigger picture of conservation. The Maltese government really needs greater political will to crack down on illegal shooting and trapping, and make sure those legal shooting quotas are strictly adhered to; a running theme in Packham's "Malta- Massacre on Migration" mini-documentary seems to be weak Maltese police enforcement. Unfortunately, a referendum in 2015 that proposed banning spring shooting of birds before they have the chance to breed saw the hunters win by a tiny margin of just 2,200 votes, or 50.44% to 49.56%. It seems the hunters still have quite a lot of political influence, but Birdlife Malta is doing a great job pressuring the government to do more, as well as educating and engaging the Maltese public about the issue. I am sure that with time and education, and maybe even some international pressure from the EU, this harmful bird shooting practice will decline.

Lastly, this whole case study reminded me that hunting is one of the more dangerous of human activities for threatened species:

Citizen science- everyone can be a scientist!

What is citizen science?
Citizen science is the collection of scientific data out in the field by members of the public to be used in larger scientific studies. A citizen scientist is any volunteer who collects such field data. Citizen scientists now participate in projects related to many areas including climate change, invasive species, ecological restoration and conservation, population ecology and water quality monitoring. 

How useful is citizen science really?
Citizen science is useful in that it can cover large temporal and spatial extents- in other words, data is collected over a much wider area and can be taken over much longer time periods. This is often crucial for conservation biogeography. Citizen science is flexible and can be tailored to each individual project, with some projects involving general members of the public and others involving specially trained volunteers that . Even children can get involved, with specifically designed projects like Project Noah allowing easy uploading of photos, geographic location and date to build a database of biodiversity of flora and fauna. Especially with children, these kinds of projects can build a sense of community with the natural and social world, a sense of self-importance and understanding that research is not just for scientists. It's similar for adults too, in that citizen science and active participation promotes citizen engagement with nature and with science.
Most practically, citizen science provides cheap source of alternative labour for collecting data considering how expensive it can be to hire scientists, graduate students and field technicians. The increasing use of the internet and phone apps has only increased the ease and accessibility for volunteers to collect data, and for projects to promote themselves.

Is citizen science accurate/reliable?
There are some limitations. In asking volunteers to identify different species for example, volunteers may can often misidentify the species, thus affecting results. But it has been argued that with proper training, simple enough data collection methods and good project design, volunteer data can be reliable. Volunteer data can be validated for example by verifying every record, or calculating error margins, meaning data can be trusted.

How can citizen science projects engage more people to become citizen scientists?
  • each project needs to have a clear hypothesis so that citizens know that the project is researching something worthwhile
  • volunteers should get feedback on their contribution so they know they have invested their time well by participating
  • develop easy participation methods, simple data collection instructions and guides as well as easy ways of sharing or submitting the data
  • incorporate citizen science into education from an early age to get children growing up with the idea that the environment is important and that they can positively contribute to scientific inquiries and conservation efforts 
  • emphasize that citizen science projects are not just useful for conservation and scientific studies, but they are fun! 
Some citizen science projects you can get involved in here in the UK:
Of course there are many more citizen science projects than these, meaning no matter what animals or plants or aspects of the environment you're interested in, there's sure to be some way to help out with your data collection. Just do a quick Google search and get involved!
