Pesticides have side effects on animals and humans. A particular  neonicotinoid pesticide is making birds lose weight . In Canadian research crowned sparrows were given low and high amounts of imidaclprid on seeds. Even birds on the low dose lost weight within six hours compared to a control group. The high amount killed some birds. It seems that appetite is suppressed. White-crowned sparrow The aves who received the low dose had transmitters attached and were released. Those on the low dose did not leave for three days and those on the high dose left in four days. The control birds flew within half a day.  It is believed that imidacloprid had to be worked out of the body. Only a minuscule amount of the pesticide stopped the birds from eating. Earlier research has shown that imidacloprid kills bees. It means the whole bird and insect family is susceptible to the pesticide. Something has to be done. Both groups of birds ate agricultural seed from crops and fattene...

Though jellyfish have no brain, intelligence is built into their bodies. They appear to act on instinct to changes in the environment. Whether they have consciousness is not known.

Rhythmically moving their heads and forcing water out from their bodies, they are a jet-propelled swimming machine. Most believe that jellyfish just drift. This is not the case, They head straight for their destination, for example, usually in groups. Somehow they know that there are others of their kind with them, though they do not have eyes.

Some scientists have suggested they use infrasound. ✴ Science by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blog...
