Since i have seen so many seaguls lately i started searching and found this;
The moniker "seagull" is ubiquitous. There are actually several different kinds of gulls, but most of us clump them under the name "seagull". In truth, it's a poor name, because seagull's aren't found exclusively by the sea. They are often found inland, and can thrive in both fresh and salt water areas. This is a good start to symbolic meaning of seagulls. It speaks about opportunity, resources and adaptability. Seagulls go where they can find the best food. They are notorious for scavenging landfills, picking over refuse in parking lots, and other garbage sites. In a symbolic sense, the seagull reminds us to move where the best resources might be. Many of us deny ourselves opportunities because we feel safe in our comfort zone. Not so for the opportunistic seagull. These birds may be a sign to fly out of our realm of comfort, maybe take a risk, and do so with the goal of finding better conditions for our well-being.
