During my walk through the Transitional Forest on 9th April I saw a flycatcher that was hawking insects either side of the narrow path at the top of Mboijaguar trail. I took a single picture of this bird before it flew up over the shrubs out of sight.
The bird was very grey with two distinct wing-bars. I could not identify the species at the time and sent the picture to Paul Smith (Zoologist/ Fauna Paraguay) for his perusal.
The bird has been identified as a Fuscous Flycatcher which incidentally is a life bird for me. Thanks Paul. Woo Hoo!!
