National park officials have sought cooperation from bird observers not to use worm to attract birds
for photography for fear that it could change the beviour of birds.
The cooperation was sought by park officials at Doi Pha Hom Pok National Park after many bird observers have used worms to attract birds to fly closer for photography, particularly at Doi Sanju and Doi Lang hills in Fang district of Chiang Mai where native birds and migratory birds will arrive in this season from January to February every year.
The use of worms to attract birds sparked widespread critism and growing concern that it could change the hunting behaviour of birds.
Park officials and conservations were concern about the hunting behaviour of these wild birds if bird observers continued to use worms to attract birds in order to get their best bird photographies.
They feared that these birds might be threatened by some opportunists who might use the same practice to catch them.
But interviews by Thai PBS of several local and foreign visitors showed both pros and cons of the action.
Most understood the park's requested cooperation to preserve the ecological systems of the park by putting up signs to prohibit using worms to attract birds.
However it was still seen of bird observers using worms ignoring the signboards at several places.
Mr Somsak Thitichayaporn, a park official said the park just wanted to seek cooperation from visitors first to refrain from attracting birds with worms.
But if they still didn't listen, there was no choice but to ask them to leave the place, he said.
