Perch my 2 parrots at the waterfront park and went for a run while wife look after. Wife was approached by security asking her to remove the birds and put into our pet carriers.
This is the outdoor and why can't we bring our birds there?
After I finished my run, I waited for 40 mins but none of the guards came to me.
Hmmm. Not impressed.
