We find that Birds travel from Country to Country everyyear and get back to their home land after spending time in cooler climates. How do they get back home? Do they have any specific Navigational modes? How will they travel during the day and also during the night?

Birds can use a variety of cues for orientation and depending on the species. Some are believed to use the sun as it moves 15 degrees / hour so it's fairly reliable. Then there are stellar cues, as most passerines are nocturnal migrants and they are a good for orientation. Geomagnetics is another way some birds find their way around, using the earths magnetic field as a guide. Different birds use different cues for navigation.

They use the magnetic poles and the stars to navigate. Yes, they will fly day and night. Many birds prefer to fly at night, as there are not as many predators out at night (hawks, eagles, falcons, etc) and it is cooler so there is less chance of dehydration and overheating.

Scientists are not in complete agreement on this subject. In fact, there has been no proven theory. All they are sure of is that birds have a device in their brain letting them know which way the poles are.

I watch the geese fly over every year and I am pretty certain the one in the front of the V formation is holding a map.
