Every year, millions of migratory birds are killed across the Mediterranean due to the intense olive harvesting practices employed on large-scale, industrial groves. The seemingly idyllic process of the olive harvest has unintended consequences for our feathered friends. The issue of bird deaths resulting from intense olive harvesting has become a concerning problem in many Mediterranean countries, including Italy, which are yet to ban this destructive practice.

Italy, with its diverse landscapes and abundant natural beauty, serves as a home to a wide variety of bird species. Many of these birds choose to make their nests in the olive trees, finding safety and shelter within the branches. These migratory birds play a vital role in local ecosystems by helping to control insect populations and spread the seeds of native plants and wildflowers throughout the groves, contributing to the overall health and biodiversity of the region.
Unfortunately, the olive harvest period coincides with the migratory patterns of several bird species, which seek out the mild climate of the Mediterranean in the winter months. To save money and time, large-scale producers often choose to harvest their olives at night when the temperatures are cooler, and the birds are resting. Bright lights and heavy machinery are used, and the loud noise and bright lights disorientate the birds. The machinery, designed to vacuum the olives straight off the trees, unintentionally sucks in these birds, leading to their tragic deaths in shocking numbers. Despite being protected under EU laws, the bird populations are being negatively impacted. Among the species at risk are the European robin, warbler, thrush, wagtail, and several species of finches.
At Nudo, we only ever harvest the olives by hand, using specialised rakes to gently shake the tree branches, catching the olives below in large nets. Our farmers do not harvest at night, and instead begin the harvest in the early morning, sending the olives to a local mill within 24 hours of picking. It’s a long and hard day's work for our farmers, but it’s worth it, knowing that we are not contributing to the devastating loss of wildlife, which must be protected at all costs.
Although initially brought to the attention of the media in , the Italian government has yet to publish any data on the number of bird deaths in Italy and has yet to enact any legislation to ban this destructive and disturbing practice.

Educate your friends and family on the harmful impacts of intense, modern olive farming methods.
Shop for extra virgin olive oil that is harvested by hand
Buy a home with land and you’ll probably have an olive tree or two on it. They’re not only beautiful and shady, but nothing tastes better than your first virgin olive oil. I well remember my first harvest.
There are several ways to harvest olives. Some are more labour intensive than others, but it is rarely worth paying someone to pick them for you. For both maximum quality (and profit), timing is vital as there can be a big difference in the grading of the oil and the price you can achieve when you come to sell them at the local olive press.

If you don’t want to pick them yourself it is best to do a deal with a local farm worker who has picking equipment, and will take the olives and give you a percentage of the oil. This is what we did last year. He came with four men, equipped with special rakes on poles that shake as they rake. He also had a piece of machinery that hoovered up the olives from the rolled ground and another that sorted them from the leaves and stones, before dropping them into the truck. It was all done very quickly.
The olives go through phases of washing and de-leafing, crushing and kneading, then the oil paste goes through a separation process, so that only the oil comes pouring out of the tap
In the years we have picked the olives ourselves it has taken us a lot longer. We don’t take olive farming too seriously, but it is nice to have enough olive oil for our own use and whatever we sell is a bonus. It usually costs us about €11 per 100kg (1 quintale) of olives to be pressed. We have found we roughly need to take about 300-400kg of olives for them to fill our 50 litre churn with oil.
After a very dry summer, not all of our trees have produced olives this autumn. This has been the case across Italy, with reports of a decrease of 11% compared to average production over the past decade. But those trees that have produced are of very high quality and the press is paying good money for them. As we have both large old trees and rows of medium size ones we are collecting the olives in two ways.
Firstly, the old trees are so large that you would need a giant to pick the top branches and they are too solid for one of those tree-shaking machines. So, nets have been put under them weighted down by big stones, so that on a windy day the olives will just drop on the nets when they are ready. Some local farmers don’t even put down nets. Instead they roll the ground flat round the tree and use what looks like a witch’s broom to sweep them up.
When we have time to lift the nets we will also rake some out of the tree from the branches we can reach. We’ll then just lift one end of the net and tip the olives to the other end, before pouring them into a large plastic bin. (Some people use crates). The olives that have spent time on the net won’t produce such a good quality oil or earn as much money from the press, but it makes good enough oil for cooking.
The smaller trees were pruned two years ago and many of them are packed with olives, especially those nearest to the river. These are the ones we hand pick. We just put a net either side of one tree, big enough to cover the drop area. Then using a small hand rake designed to mimic fingers, we comb the soft branches and the olives drop off easily. For higher branches we have a hand rake taped to a long wooden broom handle and another one on an extendable paint roller pole.
In one day of picking from 7am until 2.30pm, the fitter of the two of us filled seven bins with olives, which weighed over 200kg at the press. As they were quality olives, hand-picked that day, the press offered us €50 per 100 kg. They were sure to make good extra virgin olive oil with an expected free acidity level of 0.2%.
The sooner after picking they are pressed the better and our local press mills them within 12 hours. The olives go through phases of washing and de-leafing, crushing and kneading, then the oil paste goes through a separation process, so that only the oil comes pouring out of the tap. You can see a video of the process via their website frantoiosantoro.it
As defined by the European Commission the highest quality olive oil (Extra-Virgin olive oil) must feature a free acidity lower than 0.8%. Virgin olive oil is characterized by acidity between 0.8% and 2%. The press we use also uses a cold extraction system which means that no heat is added during extraction, as required by the EU. Oil from outside the EU doesn’t have these restrictions and so heated water may increase their yields but lowers the quality of the oil.
