I believe that the phrase "is not" is missing from the first line of the previous.
I'm privileged to provide a home for two wild caught Congo greys but I previously lived in Africa, Liberia, where we had two indigenous Timneh greys. I remember the acute interest in, and even delight by, the two birds when I realized that the nuts from the oil palm tree, also indigenous, were part of their daily delight and put the first two into their flight
Wind decades later to now and I find the black bare cores of oil palm nuts on the bottom of the flight in my back yard here in Georgia, stripped of their covering skin and pulp where the greys have taken the pulp out of the skins after removing both from the nut. I have no hesitation in doing everything I can to provide a comfortable and caring existence for these birds and will carry above the norm expense if that is what it takes to provide these little creatures a piece of a diet that they once enjoyed in the wild.
Dr. Rowan Martin now heads the newly formed Wild Parrot Trust effort for parrots indigenous to Africa and I will watch his work with intense interest. If an opportunity ever arrives to restore these two greys to their native land, I'll act immediately.
I get oil palm nuts from Jungle Gold parrot food at this link:

and it says right there on the front page that they only ship to UK and EU. I tell them I would accept responsibility for loss or damage of the shipment, perhaps due to Customs or spoilage while being held up in customs, and they agreed to ship. I recommend such a statement in the notes part of any order submitted for a United States destination or through an email to them before an order is placed.
I also recommend that one only order during the cold weather, in particular late December and January or February, to reduce the chance for loss due warmth if the shipment is help up enroute. The nuts depart the shipping point frozen and will need to be frozen again when they arrive here in the US.
In January of this year, I obtained five kilograms, or 11 pounds, at a cost of $151. They shipment was slow but arrived by DHL in apparent good order. I refreeze the nuts frozen immediately on arrival and thaw them out two at a time in a small amount of water in a microware two or three times a week to give to the birds. I would recommend that one ask for shipment by UPS if that service is available. My experience with DHL was not all that I would hope for.
And, these greys also like walnuts, pecans and almonds as well but in that order. THe almonds are the most likely to be left in the food dish; the walnuts are the least likely.
If I can answer any questions, I would be happy to do so.
