Hello

It's a birds world, with Photographer Tim Seay

I love my morning photo walks at Radke Martinez Regional Shoreline Park.  Located just off the Carquinez Strait, it is a hidden gem in the vast system of waterways in the California Delta. So many birds. So many stories to share with my camera... enjoy!

Morning Walks at Radke Martinez Park with Tim Seay

    Least Sandpiper (Calidris minutilla)

    Least Sandpiper feeding in the mudflats at low tide on the Carquinez Shoreline. The Least Sandpipers are the smallest of the shorebirds and can be identified by the yellow legs, brown upper parts and white lower parts.

    Black-crowned Night Heron (Nycticorax nycticorax)

    Black-crowned Night Heron waiting patiently for fish at the locks leading to the duck pond at Radke Martinez Regional Shoreline Park. These stocky little birds are most active at night or at dusk and can be identified by their gray/black plumage and long white head plumes. They live in fresh, salt and brackish wetlands and are the most common heron throughout the world.

    Many people regard House Sparrows as undesirables in their yards, since they aren't native and can be a menace to native species. House Sparrows are so closely entwined with people's lives that you probably will find them around your home even without feeding them. (Allaboutbirds.org.)

    American kestrel's aren't a common sight in the Martinez area, but I always enjoy seeing them sitting on pole lines in the Lodi area, as well as on the Marsh Creek Trail in Oakley.

They love open areas with shrubs and trees, but can also be spotted in forests, urban areas and backyards. They are also territorial and can be aggressive towards birds and other intruders during mating season, including fearlessly fending off hawks.

    This Great Blue Heron is a familiar sight at Big Break Regional Shoreline Park in Oakley. This adult loves to hunt for fish in shallow waters and wetland habitats, but can also hunt for small prey on land. They are patient and lightning fast when they strike.

    This Great Blue Heron is a familiar sight at Big Break Regional Shoreline Park in Oakley. This adult loves to hunt for fish in shallow waters and wetland habitats, but can also hunt for small prey on land. They are patient and lightning fast when they strike. On hot days, they will cool off by rapidly vibrating their throat muscles to cool down. It is known as gular fluttering, which can be seen in the picture to the right.
