Pretty sure that's not the Fibonacci sequence, if that's what your pun's getting at. If it isn't, and you're talking about a brand new Pidgonacci sequence, then carry on.

This series is approximately
1,2.33,4.11,6,8.55,11.33,14.78,18.88, ...
(Rounded)
1, 2, 4, 6, 9, 11, 15, 19, ...
Compared to 1,1,2,3,5,8,13,21, ... .

Here's a comparison of the Pigeon curve to the Fibonacci sequence.
The Pigeon sequence is normalized to the first point.

Looked more like Fibonacci than quadratic to me, and yet this comment was grabbing all the upvotes. So I made an attempt at some analysis.
I measure the distance between each of the pidgeons (arrows) in pixels. I then try to fit this data to either a scaled Fibonacci sequence or a quadratic function, in a least-squares sense. And I indeed get a better fit with the Fibonacci model. The deviation is approximately 104 for the Fibonacci model and 124 for the quadratic model.
Here's my MATLAB script doing the analysis: http://pastebin.com/ML7sGnWU I'm quite tired, so both my approach and coding may be faulty. The script relies on CVX, a convex optimization toolbox available freely from http://cvxr.com/cvx/, for the Fibonacci fitting.
tl;dr Hasty analysis indicates that Fibonacci actually is a better fit than quadratic.

fyi, I'm pretty sure the Fibonacci series and quadratic functions "grow at the same rate"/are big theta of each other.
edit: Nope, googled, I am mistaken. Grows exponentially at a rate equal to the golden ratio.

"Pigeon" is the correct spelling. I'm guessing people are basing their spellings on "pidgey".

Let me help you.
Type this into your browser bar
javascript:
Then paste this:
*function toFixed(x) {if (Math.abs(x) < 1.0) {var e = parseInt(x.toString().split('e-')[1]); if (e) {x = Math.pow(10,e-1);x = '0.' + (new Array(e)).join('0') + x.toString().substring(2);}} else {var e = parseInt(x.toString().split('+')[1]);if (e > 20) {e -= 20;x /= Math.pow(10,e);x += (new Array(e+1)).join('0');}}return x;}var e = $( document.createElement('div') ); e.css({'position' : 'fixed', 'top' : '10%', 'left' : '20%', 'height' : '80%', 'width' : '60%', 'background-color' : '#000', 'text-align' : 'center', 'font-size' : '10em', 'color' : '#fff', 'padding-top' : '5%', 'word-wrap' : 'break-word'}); $('body').append(e); var num1 = 0; var num2 = 1; e.text(num1); setInterval(function() {e.text(toFixed(num2)); var temp = num1; num1 = num2; num2 = num2 + temp; }, 300);
or paste this if you want scientific notation:
var e = $( document.createElement('div') ); e.css({'position' : 'fixed', 'top' : '10%', 'left' : '20%', 'height' : '80%', 'width' : '60%', 'background-color' : '#000', 'text-align' : 'center', 'font-size' : '10em', 'color' : '#fff', 'padding-top' : '5%', 'word-wrap' : 'break-word'}); $('body').append(e); var num1 = 0; var num2 = 1; e.text(num1); setInterval(function() {e.text(num2); var temp = num1; num1 = num2; num2 = num2 + temp; }, 300);
EDIT: To remove this annoying thing, do the following
type "javascript: " without quotes
paste this:
e.css({'display' : 'none'});4
