Plains-wanderer report 2019


Mitchell Plateau charter for Black Grasswren postponed to 2021

 As per previous years, Australian Ornithological Services will run a one-day charter to the Mitchell Plateau at the end of our 2021 Top End tour. It involves fixed-wing to the Mitchell Plateau airstrip and then helicopters to the campground. The plane booked is a Cessna 208B Grand Caravan (13 seats) and the helicopters are six-seat Long Rangers. This day is not part of our commercial Top End tour in that we don¹t charge our Top End participants, or the non-tour participants who elect to join them, a professional guiding fee for the day. The 2020 cost of the Mitchell Plateau charters if there are nine participants plus guide is approximately $1,032 per person, eight participants, $1,161.00 and seven participants, $1,327.00. (Please note, these are 2020 prices). Black grasswren, Kimberley honeyeater and the yellow-eyed form of partridge pigeon are the key birds for the day. It is also a spectacular flight.


In 2020 we will celebrate 40 years of
