%N "Punctual Bird" numbers n with the additional property that n-1 is not a Punctual Bird (cf. A131881).
%C Punctual Birds (A131881) are all numbers k with A132131(n) <= k < A132132(n) for some n Early Birds (A116700) are all numbers k with A132132(n) <= k < A132131(n+1) for some n

%e a(1)=1 because 1 is the first Punctual Bird.
%e a(2)=13 because 1-11 are Punctual Birds and 12 is not a Punctual Bird.
%e a(3)=22 because 13-20 are Punctual Birds and 21 is not a Punctual Bird.
%Y Cf. A033307, A117804, A116700, A131881, A132132, A132133.
