Around the estuary a saltmarsh has developed which is a zone of high productivity of polychaetes, molluscs and crustaceans, is an important breeding area for various fish species. However, it is the water birds which give the Tagus estuary its international importance. The flocks of wintering species reach up to about 120,000 individuals. The counts regularly carried out in this protected area during the winter show more than 10,000 ducks and 50,000 shorebirds. In the case of the pied avocet (Recurvirostra avosetta), up to 25% of the population wintering in Europe has been counted on the Tagus Estuary.

The many other species present attest to the biological richness and value for nature conservation in this region:

the greater flamingo (Phoenicopterus roseus),
greylag goose (Anser anser),
the dunlin (Calidris alpina),
black-tailed godwit (Limosa limosa),
hen harrier (Circus cyaneus),
osprey (Pandion haliaetus),
bluethroat (Luscina svecica),
common firecrest (Regulus ignicapillus)
Eurasian penduline tit (Remiz pendulinus).[citation needed]

In the wetlands around the estuary nesting birds include red-crested pochard (Netta rufina), little bittern (Ixobrychus minutus), little egret (Egretta garzetta) and purple heron (Ardea purpurea), marsh harrier (Circus aeruginosus], Montagu’s harrier (Circus pyagurgus), black-winged stilt (Himantopus himantopus), collared pratincole (Glareola pratincola) and little tern (Sternula albifrons). While the associated redbeds contain great reed warbler (Acrocephalus arundinaceus), Savi’s warbler (Locustella luscinioides) and other warblers. The nearby fields have stone-curlew (Burhinus oedicnemus) and calandra lark (Melanocorypha calandra) breed on adjacent farmland. Little bustard (Tetrax tetrax) occurs all year but is more numerous in winter. Raptors which may be seen over the fields include black-winged kite (Elanus caeruleus), short-toed eagle (Circaetus gallicus) and booted eagle (Aquila pennatus).

Nearby patches of woodland hold short-toed treecreeper (Certhia brachydactyla), European nightjar (Caprimulgus europaeus), red-necked nightjar (Caprimulgus ruficollis), Iberian magpie (Cyanopica cooki) and many passerines.

During the Spring and Autumn many species stopover on the Tagus during their migration these include curlew sandpiper (Calidris ferruginea) in large numbers with many other shorebirds in smaller numbers, common redshank (Tringa totanus) and black-tailed godwits reach their peak numbers during migration too. Other migrants which may be seen include Eurasian spoonbill (Platalea alba), Mediterranean gull (Larus melanocephalus) and black tern (Chlidonias niger) and many passerines.[3]

Certainly! The **Tagus Estuary Natural Reserve** is a remarkable area close to Lisbon, Portugal. Let me share some interesting details about it:

– **Location**: The Tagus Estuary Natural Reserve, also known as *Reserva Natural do Estuário do Tejo*, lies on the south bank of the Tagus River. It’s surprising to find such a vast nature reserve right on the city’s doorstep! The reserve encompasses the **largest wetlands in Portugal** and covers approximately **14,192 hectares**³.

– **Habitat**: Within this protected area, you’ll discover extensive estuarine waters, mudflats, marshes, salt flats, and alluvial agricultural land.

3. **Eurasian Otter (*Lutra lutra*)**:
– Otters are semi-aquatic mammals that depend on clean waterways and abundant fish.
– The Tagus Estuary’s marshes and freshwater habitats support otter populations. Ensuring water quality and protecting their habitats are crucial for their survival.

4. **Common Tern (*Sterna hirundo*)**:
– Although not globally endangered, the common tern faces threats due to habitat loss and disturbance.
– The estuary’s mudflats and sandbanks serve as breeding grounds for these elegant seabirds. Conservation efforts help maintain their nesting sites.
