If they’re approaching a tree, nest, feeding area, rooftop, field, or body of water, they may gradually lower their altitude.
A bird flying low may simply be getting ready to land.
They’re Traveling
Through a Familiar Route
Birds don’t always fly at the same height throughout an entire journey.
A flock might travel higher over one area and then descend as it approaches a feeding ground, nesting site, roost, or water source.

Why Are Birds Flying Low Over Water?
Birds flying low over water can be especially fascinating.
You may see them skimming across lakes, rivers, ponds, or the
ocean with their wings just above the surface.
There are several reasons this happens.
Water can be an excellent place to find food. Some birds search for insects, fish, small aquatic organisms, or other prey near the surface.
Other species naturally travel close to the water while moving between locations.
Some birds also have flight patterns that make low-level movement over water perfectly normal. ChooseBird Feeders
So if you see birds flying just above a lake, don’t immediately assume rain is coming.
They may simply be having lunch!
Why Do
Flocks Suddenly Fly Very Low?
Seeing one bird flying low is interesting.
Seeing an entire flock suddenly drop closer to the ground can be downright dramatic!
There are several possible reasons.
A Predator Could Be Nearby
Birds are constantly watching for danger.
A predator such as a hawk or falcon can cause a flock to suddenly change direction, scatter, climb, or dive.
From the ground, it can look like the birds are moving as one giant organism.

they’re responding quickly to a perceived threat.
They’re Following Food
If insects are concentrated close to the ground, several birds may gather in the same area.
You might see an entire flock swooping repeatedly over grass or fields.
This type of behavior can make it seem as though the birds have deliberately chosen a very low flight path.
They’re really just following the food.
They’re Moving as a Group
Flocks often travel together between feeding areas, nesting locations, water sources, and roosting sites. OrderDNA Kits
Their altitude can change several
times during a single journey.
A flock flying low doesn’t necessarily indicate anything unusual.
