Besides for anti-immigration activism, Birdwood remained involved with the ABN. For the Captive Nations Week held in Britain in November 1969, she served as the lead speaker for an ABN conference in London, where she called for the British government to fight to free all of the "Captive Nations" of Eastern Europe. At the end of Captive Nations Week, she was the lead speaker at an ABN rally in London, where she called for a moment of silence for "95 million victims" of Communism and spoke about her concern for the "Captive Nations".
