For me nothing is as pleasant as laying in the grass on a warm summer day in good distance from human activity, looking at the sky and listen to the wind wipe the grass until I fall a sleep.
This is something I did the 30th of July 2017 when I decided to visit places I remembered as a child, almost 50 years ago. It was at my grandparents´ farmland, Efri-Brú, which they owned most of the last century.
About 2 km northeast of the farm is a place named Hvítingshæðir. There is an old ruin of sheep shield, surrounded in grass field and remnants of old fence. This sheep shield in Hvítingshæðir was one of three or four sheep houses in distance from the main farm buildings. These sheep shields were usually built in places where it was easy to mow and keep hey for sheep during the winter months.
There is not much going on in this recording. Many decades have passed since farming was in the area and most birds are quiet this time of the day. So gust is playing the main role in the recording.
This was one the first recording I did with my parallel MKH8020/8040 AB setup in Rycote windshield. It was recorded on four channels with 50dB gain and HPF at 80Hz.
Quality open headphones are recommended while listening at low to mid level, or in speakers at low level.

Wind is very often the recordist´s enemy. Especially if the rumbling noise of „hammering membrane“ is not acceptable.
Some recordists may say this rumbling noise is just normal. Everyone will hear similar rumbling noise when they stay in wind.
For me it sounds like „clipping distortion“.
Wind protection is one of the most important thing for nature recordings, especially in the country where wind below 3m/sec. is almost unique.
I have tried several wind protections. My own, Rode Blimp and Rycote Softie and Modular series. All of them sounds similar. So it was welcomed when Rycote introduced the Cyclone windshield. Cyclone have Floating Basket Suspension, which is very nice. Until now, it has been only be used in the overpriced Cinela products.
Rode NT1a is one of the best cardioid microphones available today for nature recording. But sadly it is not build for outdoor use, so it has some poor futures like handling noise.
So when I choose it on the field, it has been important to keep it in Rycote modular windshield, place it close to the ground (sadly very often too close) and pray for completely calm weather. Then pray again for nice outcome.
I per-order a pair of Cyclone mini windshield last summer and got it in mid September. My plan was to fix them with parallel MKH20/40. But I also gave my modified NT1a a try when I saw it was almost „plug and play“ to fix it .
Without fur Cyclone was not far from to be equal to Rycote modular series with fur. But when Cyclone was dressed in fur the rumbling noise almost disappeared in wind around 5-7 m/s. That was a huge success.
Following recording is a short part of overnight recording from Stafholtstungur, in the west of Iceland. The gust goes up to ca. 7m/sec. and the recorder HPF was set at 80Hz. The rig is about 1 meter above the ground.
Some rumble noise is audible in this recording, but some of it could as well be a vibration from the tripod. Keep it in mind this is NT1a which is particularly sensitive for handling noise.
I will spend more time to test this setup but it looks like I need to order another pair for my MKH20/40 rig.
Quality open headphones are recommended while listening at low to mid level.
