Seagulls

What they eat:

Gulls, or Seagulls as commonly called, feed on little land and water animals. These normally include aquatic animals, terrestrial invertebrates and small vertebrates, plant remains, carrion, and refuse.

If near the sea, they may also frequently eat the eggs and young of other nesting seabirds.

Migration patterns:

Seagulls are known to be short to medium-distance migrant birds. Depending on where they breed, they will often head south or remain near the sea during winter months.

Where they tend to live:

Seagulls live all over. Their knack for scavenging take them anywhere where there is food. They roost and loaf around, often in large packs in areas where they have good visibility of potential predators.

From athletic fields to beaches, to parking lots, to airport runways, you can normally find seagulls most places where they feel safe from terrestrial predators. City rooftops are a very common hangout spot for these birds.

Nesting:

Gulls often pick nesting sites which contain soft soil, sand or short vegetation. They nest on the ground and usually produce 3 – 5 eggs per bird.

These birds will choose to nest near rocks, logs or bushes to protect their eggs from the wind and potential predators.

Possible Health Concerns and Damage:

The growing seagull population in North America has brought about a variety of problems for different parts of society. They are the source of much of the damage to agricultural crops and threaten human safety on a daily basis at airports. It is not uncommon that gulls are involved in collisions with planes.

Furthermore, the constant presence of seagulls near holding reservoirs increases the potential for disease carried by these birds to be transmitted to the human population.

They may be aggressive in their scavenging efforts if they see people eating food outdoors.

They also act as predators to other seabirds during breeding season. The sheer number of gulls preying on these types of birds can affect their breeding performance, possibly becoming detrimental to the other species affected..

Lockbird recommends the following deterrent strategy:

Audio Bird Repellers: While this tool does not work forever, it may be good to use as an initial harassement strategy. If the seagulls perceive a predator bird to be in the surroundings, they will want to disperse. 

Lockbird T-300: If the seagull problem is quite persistent and these birds are causing lot's of damage to your property, it may be worth looking into buying or renting a Lockbird T-300 laser tower to repel these birds from your property. This automated laser tower is quite effective in environments with a large surface area.
